interesting to find this group and glad to see it seems to be active.
i've had a box of WWII patches from my dad for years and just cracked it open again to check the contents. the box itself is pretty neat in that i believe it is a WWII Red Cross parcel 'LYOVAC' dated (expiration) Aug 5, 1948.
if i remember the story from my father, after WWII soldiers were allowed to keep their uniforms as civilian clothes, but they had to remove all the military patches. for a while, my dad was one of the officers supervising this operation.
apparently the 2nd Army were a good deal of their customers, but my dad also mentioned that box followed him around for a while and he often traded patches with other men. in total there are probably a few hundred along with some buttons and insignia. very cool stuff i'm interested in learning about.
other items i have are a few flags, US, Nazi, Red Cross and a German submariners suit. i have an old picture of my mom wearing it shoveling snow. apparently warm and waterproof.
