I have 2 S&W inherited from my father who was was retired police. The first is 38Spl Military&Police 2nd Model 1st Change manufactured in early 1900's. Wondering about restoring it as nickel plating badly worn and grips and grip screw are replacements. Piece functions well and have shot it on a range. History is that it originally belonged to a relative who had been a county sheriff in Indiana early 1900's and later helped start Indiana State Police(Called something else originally) and in the 1920-1940 era was proprietor of private detective agency. Some pitting in barrel but still wonder if worth restoring or best to leave as is............The other is 38SW New Departure First model which I'll make posting about in the right place.....Thanks for any input....
