I remember seeing guns that were converted from fixed to adjustable sights. Maybe around the 70's. I would not know how to price one. I saw a pre-WWII Heavy Duty, with adjustable sights stamped "Micro", and a Target-type hammer spur which did not look like it came from the factory. Probably converted sometime after WWII since Micro did not exist until the founder of Kings Sight Company passed away in 1945 . I can make a guess on the value of the gun, but with the conversion, not so much.Back when the Earth was young and so was I, a favorite pastime was reading gun rags of the day and drooling over pictures and stories about up grading and adventuring with cheap, relatively common old S&W revolvers with adjustable sights, special grips, barrel and even caliber modifications. Then as the last of the woolly mammoths disappeared, a new generation of collector investors came along and such practices became frowned upon. I miss those days!

Even just an after-market front sight insert seems to turn people off. Then on the other hand, throw in a gold box with a random number not matching the gun, and the price jumps a few hundred dollars...
