Mk Va, R7347, USA Summer 1941



Spitfire Mk Va, R7347, assigned to USAAF for testing, Summer 1941

It seems there is always much to learn about the Spitfire.  When my interest in the Spitfire first began, I probably did what most modelers do:  I made a list.  The list started with Mk I, followed by II, III, IV, et cetera until I thought (wrongly at the time) that I had the full List of All Spitfire Marks that began with I in 1939 and ended with XVI in 1945.  I filled it in as I read about the different marks and where they were used.  Rarely did I see the II, never a III or IV nor a VI; an occasional VIII, lots of V and IX.  No X, XI or XIII.  No XV.  Oh joy, it’s really not a big list so it won’t take me long to make one of each just to see what they looked like, in the flesh (plastic) which was all I’d expect given how rare they are.

Then those darned suffix letters cropped up.  What could that be?  After nearly a year of reading and collecting books I realized it was the armament...sort of.  And the Mark number was basically tied to the engine...sort of.  Some other minor refinements came to play as well.  Suddenly my list grew.  And I hadn’t considered where the PR variants fell, nor those prefix letters.  That's a story for another day...

The Mk V came about as a response to the Me-109F.  Faster and higher flying than the Emil it was replacing, it outclassed the Mk I/II in frontline service with the RAF in 1940-41.  Like any good aircraft manufacturer, Supermarine was working with the RAF to develop a better Spitfire in the guise of the Mk III.  However so many improvements to the basic airframe as well as a new engine meant critical delays in production and one must remember that at the time, the RAF was licking its wounds from the BoB and facing Rommel in the desert.

So the obvious question was asked, “What if we stick the new Merlin on a Mk II airframe, and do it such that we don’t have to modify the airframe so much?”  The engine in the Mk III was the Merlin XX; which was needed for the Hurricane II so an uprated Merlin 45 that was based on the Merlin III was chosen.  It fit the cowling of the Mk I/II and just needed some slight mods that were easy and quick to implement.  The engine was “hotter” so needed a bit more cooling...the larger oil cooler from the Mk III would do.  A bit more torque so we’ll need to stiffen the fuselage...that’s a bit easy.  The Mk V was born and would be a short production run until the Mk III was ready.

History tells us the Mk III was cancelled and the Mk V the most produced single Mk of the Spitfire family (if one doesn’t combine the Mk IX and XVI production).  So much for an interim type.

The Aircraft
When Mk V production began, the cannon armed wing was still causing problems.  So initial production was the 8-gun Va. The intent all along was to make the Mk V a cannon armed variant. Some Mk V were conversions from earlier Mk I/II airframes.  Later in 1941 when the cannon armed “b” wing was fixed most surviving Mk Va aircraft were retrofitted to the Vb standard; as well as any Mk Ib/IIb that were still operational.  Some didn’t but those generally were no longer considered front line aircraft and were used for OTU duties.
R7347 was one of the last of a batch of Mk I’s ordered as Mk I’s but delivered as Mk Va.  Delivered in April 1941 to 39 Maintenance Unit, then transferred to the USAAF for testing at Wright Field later in April 1941, arriving in November 1941.  It remained there for testing until January 1943.  Unfortunately, I do not yet know the fate of R7347.

The Model
There are currently three alternatives for making a Mk Va:
  1. AZModel (limited run, limited availability but a very nice model)
  2. Airfix Mk I/IIa (contains the parts but no instructions)
  3. Bash together a Mk I/IIa with a Mk Vb to get a Mk I/IIb and a Mk Va (been there, done that, it didn’t work for me)
I have the AZModel kit but I’m reserving that for the usual Va subject, Douglas Bader’s W3185/DB that he was shot down in while over France in 1942.

The recent tooling by Airfix includes not only all the parts necessary to model the Mk I and Mk II, but the larger oil cooler for the Mk V as well as the proper De Havilland prop.  When first released in 2009 there was speculation that a Mk Va was soon to follow, but after 3 years still no Mk Va from Airfix.  So it was off to the spares box for decals.

It turns out the AZModel boxing has the decals for R7347 when tested in the US.  That certainly makes this all very easy. 

Construction is straightforward, but use part numbers 41 and 42 for the oil cooler, the round exhausts parts 21 and 22, and the DH prop.  Photos show the IFF aerials, so I drilled 0.1mm holes on each side, at about frame 17.5.  That is about 12 inches forward of frame 18, which is the extreme trailing edge of the wing/fuselage fairing.  I then measure up 9 inches from the horizontal stringer that aligns with the bottom of the cockpit door.  My method for installing these after all painting and decalling is done, is to superglue one end of the invisible thread into the elevator hinge line (underneath where you can't see them) and once cured run each into the holes.  Using tweezers I pull the IFF antenna taught through the cockpit opening and put a drop of glue to hold them.  I then put the canopy on. You won't see them on this model as I didn't put them on...frankly I forgot and the canopy is on, so there you have it.

Now, technically when on the ground the IFF aerials should be disconnected from the horizontal stabilizers so a ground mechanic or plane captain cannot accidently break it; but it looks "wrong" to me as a model when done correctly because it appears the antenna are broken off. 

Painting is standard Spitfire scheme for April 1941: Temperate Land Scheme of Dark Green (Humbrol Hu116), Dark Earth (Hu29) with Sky (Hu90) undersides, spinner and fuselage band.  I used acrylics throughout.  Night serial and no squadron codes.

Summary
An easy build, albeit I didn't do this one over a weekend, I could have had I wanted to.  I spent extra time on it and unfortunately the build got delayed by 3 months when I transferred due to a job change.


Thanks for looking...

Airfix Spitfires




Airfix released 23 Spitfires in 4 scales over the last 57 years and their objective is to release one of each mark, in 72nd scale anyway. As the premier kitmaker foe Britain youd think their kits of their most iconic aircraft would be the best there is.   Unfortunately, some have been pretty horrible as either kits, Spitfires or both. Most are accurate, albeit detail is usually sparse (in the smaller scales anyway) and if one gets past the construction issues a fine Spitfire can be had. 
In two parts I'll cover all 23 to date, in this first part I'll cover the lone 100th & the 72nd scale kits. Next month I'll cover the 48th & their 24th scale kits.  Most of my information on dates and kit numbers are taken from The Airfix Tribute Forum. 
100th Scale
Okay, technically not Airfix, in 2007 they released under the Airfix label the Doyusha tooling of a Mark Vb as kit number T1002.  Considered “pretty good” they typically come pre-painted and sometimes are released with a motorized prop. 
72nd Scale
pastedGraphic.pdfAirfix began their aircraft models with a release of the BT-K in 1955. Based on the Aurora kit, it was scaled down to 72nd.  It is a very basic kit; its shape is definitely a Spitfire albeit not the most accurate; it is more for the beginner or nostalgic modeler. Only available until 1959 when it was replaced by their first Mark IX and is a collector's item today. The kit number was 1316, which is the same number for their Mark IX. 
Not to be confused with their first true Mark I, released in 1979 as kit number 01065, and re-released in 2003 in the BT-K bag. 
pastedGraphic_1.pdfIn 1959 Airfix released a Mark IX to replace the BT-K Spitfire. Also not very accurate it had markings for Wing Commander Johnnie E. Johnson's Mark IX. Originally kit number 1316, from 1988-2007 it was listed as 02081 and is generally available. Referred to as "the JEJ kit" it only looks like a Spitfire if it's the only one on the shelf. 
Airfix released a Mark Vb in 1975.  Still regarded as very accurate in shape and exterior detail. Of note, the raised detail is considered by purists to be the most accurate representation of the lapped joints along the panel lines. However Modelers in general prefer engraved panel lines, even if the most crisply done are actually over scale.  Still available as kit number 02046. 
pastedGraphic_2.pdfA Mark Vc was later released in 2005 by adding a sprue to the basic Vb kit representing the revised wing armament. The new kit number is 02040.  Unfortunately the wing is overly thick and suffers engraved panel lines not in keeping with the Vb kit. The good news is a tropical filter is provided as well as parts to modify the fuselage to a Seafire, which were added in 2009 for an Airfix Club FAA release. The decals are also quite good. It's apparent the Vc sprue is just a scaling down of their so-so 48th scale Spitfire/Seafire kit as it can also be made into a Vb, Vc or Seafire Ib, IIc or III; suffering from the same faults as the 72nd boxing.
pastedGraphic_3.pdfIf one can find an Aeroclub c wing, which is quite good and was specifically designed as a replacement part for this kit, a very accurate Vc, or Seafire IIc can be made. 
As mentioned earlier, in 1979 Airfix released a new Mark I, much better in shape than their earlier BT-K. This new kit was very similar in quality to their Vb kit.  The Mark I and their Vb were the basis for all aftermarket products to upgrade, convert or super detail an early Spitfire for the next 20 years. Originally listed as kit number 01065, renumbered a few times but mostly as a variation of 01071, don't be confused by the recent (2010) A01071A that is a new tooling.
pastedGraphic_4.pdfAfter Hornby bought Airfix they pledged to keep the label.  Eventually they released a new, modern tooling of the Mark I in a new red box. Very accurate in shape it also sported a highly detailed cockpit. It's only drawback is overly wide and deep panel lines; it seemed Hornby hired the Matchbox engraver!  This kit is available in both a starter's kit as well as the original and is considered more accurate even than Tamiya's Mark I. Kit number A01071A.  Also included in sets 55100, 50128, 50135, and 50143. 
A company called 3D-Kits shortly thereafter released a double sprue set containing an improved seat, control column, Coffman starter bulge and DH prop to allow conversion of either this new Mark I, the older Mark I or even the Tamiya Mark I to a Mark IIa. Also included were decals for 4 machines. 
In 2011 Airfix released this kit with an additional sprue containing parts to model an early Mark I (2 bladed Watts prop, flat canopy, pole antenna) as well as a Mark IIa (Coffman starter bulge and DH prop). Although no decals are in the box for it, the Rotol prop and enlarged oil cooler are on the sprue to allow the modeler to make a Mark Va. Unfortunate for 3D-Kits who now offer just the decals. Kit number A02010.
3D-Kits does offer a nice conversion for this kit to make the Mark IIa LR (long range). Just a simple conformal fuel tank for one wing, it includes decals. 
pastedGraphic_5.pdfIn 2009, Airfix released a Mark IXc to replace their 1959 tooling. Long needed in 72nd was an accurate kit and Airfix did not disappoint, however it was not as good, overall, as their recent Mark I. No cockpit to speak of, very similar to their toolings from the 1970's with a recliner for a seat and a plastic semicircle for the instrument panel, not even a decal!  Sporting similar deep panel lines, they weren't quite as bad as the Mark I. Parts were in the box to make an early or late Mark IXc and even a post-war mark, however only the wheels for a late Mark IXc were included (4 spokes). The prop is a bit anemic but is passable and the decals are very good.
pastedGraphic_6.pdfAlso in 2009 a PR Mark XIX variant was released, their first Griffon engined kit in 72nd scale.  Kit number 02017, it is very similar to the Mark IXc in detail, it does suffer from being too short by about 4 scale inches (it's the length of a late Merlin Spitfire, not a Griffon). Still a very nice kit to build, it's a toss up whether to improve this inexpensive kit or to pay top dollar for the difficult to find Fujimi XIX that also must be converted, albeit from a F Mark XIV. 
Not yet available in the US, Airfix announced a F Mark 22 for release for 2012, I'm still looking for a reboxing of their Mark I/IIa/Va as Wing Commander Douglas Bader's Va he was in when he was shot down and taken prisoner in 1941.

2012 Goals



Okay, 2011 was a very good year for me.  Nine Spitfires/Seafires completed!  I've got an ambitious 2012 planned as I've indicated over on my other blog; but only 5 Spitfires/Seafires are in the mix:
  • CMR Seafire XV
  • Airfix Spitfire Va (new tooling)
  • Airfix Spitfire II LR (new tooling)
  • Airfix Spitfire IXc (new tooling)
  • Sword Spitfire Vc
I've got a Sword Mk XVIe on the way, and I may put that in and take out the Airfix Mk IXc.  It all depends on my progress with the others, the Airfix kit is so easy/quick it's almost a weekend build.  Of course, I have that box of parts waiting for me to carve and glue a Spitfire Mk III from, but I still have quite a bit of information gathering to do on that one, like paint scheme and where exactly to cut the wings, for starters.
