About 2" across and 1 1/4" tall with double butterfly clutch pinbacks. It has the clutches which I removed for the photo of the reverse, which was tricky to get. Has light wear, spot on the warhead, I haven't made any attempt to clean it. It is a stamped pin. I don't know the age but it is possibly sixties, I did not find another just like it available. So jump on it.
