Bill, that is interesting then isn't it. I've found three I think at various dealers, already sold, but all were brass.
I don't recall where I got this picture as I saved it a while back to use as a reference, and thought it was a brass badge. From what you say, maybe it is just the light that gives a silver badge a yellow appearance?
I would like to get one for my women's army collection, but for now there are too many items ahead of it, and I need to complete those deals first. But it's on the list.
