For your consideration is a vintage C.M.A. (Chemical Materials Activity) pin. This pin has the butterfly clutch and no other markings. It is 1" long. The Chemical Materials activity unit was and is responsible for the stockpile of chemical weapons as well as destruction of them.
I have recently acquired an estate with a lot of military pins, awards, etc. The gentleman of the estate was in WW2 and his father was in WW1. Items are listed as found. I have not cleaned them. Check my other listings for more from this estate as well as other vintage, antiques, collectibles, fabrics, clothing, holiday and more.
