I picked up a nice pre-27 S&W with a S 96xxx Serial no. this past weekend. The gun had a set of the diamond target "coke" grips on it that were not numbered but had obviously been on the gun for a long time.
Can you help me with date of manufacture- I'm guesssing '54 or '55 - and if the target grips could possibly be orginal to the gun or did they have to be a later addition?
1953. Target grips usually were not numbered. However, 1953 is too early for "cokes". They started around 1956 with the 44 Magnum.
Correct grips in 1953 would be diamond magnas or Non relieved diamond targets, but I wouldn't complain about having "cokes".
