The listing, RISDON HUGE KEY-TAG SAFTY PIN has ended.
This is a Risdon key-tag from like the 50's you could just look up that name and get the history info. on them they were one of the first clips used in the army, laundry places, hotels, there is a lot of history on them i only have one i had gotten from helping cleaning out my great uncles place after he past, he had all kids of weird stuff and i thought this was neat.It is just about 5" long as you could see in the pictures and the marking on it.
