I honestly don't remember. I was probably in REVOLVERS and MANUFACTURER = SMITH & WESSON, then looking at used for under $150. There are probably more efficient methods. I look for bare frames pretty often and rarely find anything.
Getting the frame with matching side plate was a real plus. Fitting a new one can be a real trial. I don't think I would want to even begin to do it. I'm impressed with your whole project and how you went about it. BTW, how long did the project take to find the parts and complete all work?
