Great stuff!
I've always particularly liked the 'Communications set' with the man kneeling down by (or inside?) the phone box. When I worked for Foundry in 1999 I remember one of the Perry twins telling me about it - he'd just sculpted it. I think he mentioned a paper boy running with a message as well, but apparently that didn't get made.
I've got these figures myself, and have yet to paint them.
I doubt that you'd need a lot of actual, trained German soldiers to give the Walmington on Sea lads a very hard time -- possibly a small patrol --- H
