A friend of mine was in a pawn shop today. He knows I collect S&W revolvers. He sent me a link to the shops web site, so I could see the gun in question. They have it tagged as a 4" model 48. I could clearly see it was not a K frame but what looks to be a J frame with a square butt, wearing diamond magna grips. I could also see the barrel is marked 22 long rifle. It has a pretty tall front ramp site and a rear adjustable site. It is blued with I believe a 4" barrel and it appears to be in 95% or higher condition. I looked in my 3rd edition copy and I believe it is a Model of 1953 I frame pre-model 34. What would be a reasonable value for that model these days?
