In the late 40's early 50's Vickers produced a series of vehicles, and I'm looking for data on them.
They're the so called FV-300 series.
http://en.wikipedia.org/wiki/FV300_Series
The one's I'm most interested in are the FV301 Also called the A-46 light tank, and the FV-304/FV-303 (They both look identical apart from the weapon, so Find the details about one you'll get the info about the other.
Any ideas, books or sources to try? Has anyone come across any mention of them?
Please note:
I'm stuck. I've tried the usual suspects of Bovington, Imperial War Museum, National records office and BAE systems (They ignored me, possibly because I wasn't a dictator wanting to murder large chunks of my population... Soon BAE, Soon!

).
I've tracked down the Vickers papers, and am trying to get access to them, but they're spread all over the Midlands, and the holders are none to fast at responding.
Yes, I've also tried google and am aware of the appropriate websites, such as Henk and Arcane AFV's..
Thanks.
