Hi Migs
I doubt if the Aurora people had ever heard of a PR Spitfire. Back then it seems that the going thing was just a "British Spitfire" and Battle of Britain and that was it. It was actually Airfix I think that got modellers to realize that the Spit was continually developed through the entire war and was a front line fighter still in 1945. No other fighter a/c had that distinction, not even the Me 109 which was pretty well at the end of it's development with the 109 G. The Luftwaffe pilots by then called it "the Bulge".
The later Aurora box art isn't too bad considering, but of course a Mk Vc would never have been painted in BoB era paint scheme, but BoB was synominous with the Spitfire still, especially with Yanks.
The "c" wing was almost always seen in what you call "b" configuration but really that need not be said as it was standard loading on the "c" wing. Very few Spitfires loaded all four cannon in a "c" wing. It was just too heavy. The "c" wing had other advantages over the "b" wing such as the u/c raked forward a couple degrees and the ability to fit bomb carriers (Yanks call them "bomb racks"...in the Spit manual it is a "bomb carrier") on the wings for 2 X 250 lb bombs. The belly bomb carrier could take 1 X 500 lb bomb so then you had a 1000 lb bomb load on a short range a/c that could really defend itself after bombing the target. Later the "e" wing, which was loaded with 2 X 20 mm cannon and 2 X .50 cal machine guns, was introduced. The change was in the armament, not the wing. The basic "e" wing was really the "c".
Bottom line---The Spitfire is one complicated a/c to study but there have been many who instead of researching further, have reorted to "guessing" and I am not refering to just people like Cuda, I am talking about books such as the awful Squadron attempt and Osprey's terrible Spitfire modelling book by someone who hasn't a clue about Spitfires and misleads everyone into believing them once their gusses are in print.
My Spitfire library is up to 85 books now and some are not worth the paper they are written on while others are indispensable. I also have shop manuals for the Mk V, Mk IX, and Mk XVI and the engineering drawings for the Mk V and IX along with the Vickers factory Spitfire painting drawings and diagrams for markings. I have worked on real Spitfires from 1976 to present (a Mk IX and a Mk XVIe).
