Same Wisconsin soldier lot. He apparently was very proud of his Carbine Expert Marksman qualification since he purchased 3 badges. (On the reverse perspecitve):

I know the first is a clutch back. I don’t really have any questions on that one.

The second one has a catch that looks like one you would see on a German badge.
What is the significance of this? Period repair? Overseas manufacture?

I have never seen an attachment pin like the one on the far right? What is that and what is the significance?

Again, any help would be greatly appreciated and thank you!
