BEF and others would be great, especially as I've just acquired some Bren and scout carriers from Butlers Printed Models, I had to use old Airfix figures to make the crews https://www.butlersprintedmodels.co.uk/
A couple of pictures
I do like your Scout and Bren gun carriers.I find these very attractive vehicles having seen them a while ago. I have not come across this manufacture before . Certainly food for thought a I am considering modelling them in 15mm.
Lots of universal carriers in 1/72 but these carriers are not readily available. Currently, converting some PSC universals into scout and Bren gun carriers as after buying the box I realised that universals were post Battle of France.
