Thanks for the input... we will do some research on the Valentine to see which variant(s) can be included in a single kit.
What's your view on which Valentine variant(s) you want us to do?
I'd like to address this. I think the kit should include parts for a Mark II and/or Mark III (with sand shields, fuel tank etc), and a Mark IX. This would give you a common Desert War version and a (useful) version used by the Red Army. It might also be possible to squeeze in the parts for a Bishop (it's a horrible looking vehicle and a mediocre SP gun, but it would be a nice option to include). Once the chassis is done, you could also do the Archer, which would (I suspect) be reasonably popular.
