Hi Hammer Down,
You seem to be the S&W Revolver expert, so I hope you do not mind if I pick your brain also. My revolver (inherited from my Father) is similar to those above. Blued, with a checkered grip. It has 38 Special CTG on the barrel. I can not find a model number or patent dates anywhere on it. I found the serial number (matching) under the extractor and on the bottom of the grip. The serial number is 2628XX. I am interested in knowing the model and date of manufacture. I have NO intent to ever sell it, but would appreciate an approximate value. The blueing is 85-90% and the grips are excelent. Thanks is advance!!
