Apologies slightly late but bolt action is a good option. I have and will use it and CoC to do VBCW and there is a very helpful pdf of VBCW type equipment (Very British Civil War with Bolt Action by Al Morrison) and one of the points values (Vehicle points value by Richard Humble, Bolt Action Alliance) so you can make your own armoured things
if you want them PM me as they are useful and quite transposable to your chosen theatre of belligerence.
