Excellent figures but I think there are couple of things you could do...
1) The weapons, change them for stens and re-work the slings using lead-foil, even a civilian shotgun would be acceptable.
2) The armbands, remove them and replace them with lead foil
3) just a personal feeling, but the jackets could be extended 2-3mm, jackets of that period would be longer and even baggier
4) The trousers would be baggier as well with flaring or even turn-ups on them
As you mentioned, you wanted some suggestions...

Looking very good at the moment but need a bit of work..JIm
