I've got this..
My Grandfather cut it off of a Luftwaffe officers jacket in a Pub in France. The germans had literally just run out of the backdoor as there were cigarettes still burning in ashtrays and there were half drunk drinks on the tables.
I also have a coin which was in his wallet when he got shot and it deflected the bullet. The coin is a right mess but it saved his life, I'll get a pic of it.
EDIT: Gutted! Can't find the coin, will have to see my mum I think..
