Yeah, I'm not exactly sure what it is, but it appears to be a Model 60. Definately no 0 after the 6 though. One of our Trooper's got it from her grandfather. It's all stainless, 100% engraved with aged ivory grips. The serial number is on the bottom of the grip and on the the cylinder. I was warned not to place the entire serial number on here. I was just trying to get the date of manutacture for the Trooper.
The first of the SS model 60's were made in 1965 and would not have the Ser.# on the face of the Cyc. as seen when loading. Sounds like you have a nickle Chiefs Special, a Model 36. If so, based on the Ser.#, I'd say 1954ish+/- hhowever S&W didn't model mark their guns till 1957. Pics and a further description would help such as: is the Ser# on the underside barrel flat, how many screws, flat latch? Etc. Brad
