Hi Amy and Terry
Thanks for your reply. I've found a certificate for this group on eBay but it's a lot of dosh for a piece of cardboard! Mind you. they've been trying to flog it for some months now....
I think that they fit in to what passed for welfare for members of the armed forces.
The badge uses a very unusual form of construction (for a lapel badge) with its hollow backed effect and then Fenwick's maker's mark in raised letters. A rather elaborate way to make this type of badge from what I've seen of similar items.
Mike, you always seem to have the gen on this area. Any clues?
