There is no J prefix in front of the serial # ,flat latch, diamond grips, gun is unfired , no box, Iwas also wondering what it is the value of this model?I bought it for $535.00 at a local gun show. Thanks and SEMPER FI!
Flat Latch is a dead givaway, mid 50's. I have my father-in-laws off duty M-36, he was appointed in 1955-56. Your gun looks mint, my dad's needs to be refinished. I'm thinking of sending his and mine (1979) to S & W and have both refinished by them.
