Mine is just like yours, except that mine is from 1971-72 and was carried/used before I bought it.
It's been used a bit more and carried a lot more now.
Got one of the old ones here somewhere. There it is. Both of my pre-1960 ones are pretty well used relative to carry, but not fired much. This one dates around 1956. The original owner was proud of it and had his name expertly engraved on just above the grips.
Nice flat latch Chief, DocB. I bought mine from a pawn shop in Rockdale County, GA.
I had a Chief's Special cap gun as a boy and always wanted the real thing.
Mine is almost as old as I am, and I carry it daily.
