I have a nickle 3 inch round butt model 10 with a 17d prefix in the serial number which should mean a 1982 year of manufacture. The gun is in excellent condition. The only other one of these I have seen was in what I believe was a picture posted by Smithnut in a 3 inch k frame thread . This made me wonder if anyone would know how many of this variation was made ,and if it would be worthwhile to letter this gun.I know it doesn't count without pictures but I am a little behind the times on this computer stuff and think it is just a passing fad so I haven't learned to post pictures yet. The gun has the letter N on the cylinder and frame butt which convinces me it is factory nickle. I hope I have posted in the right place because I would hate to anger the gorilla. By the way I met Lee Jarret at OGCA a year or so ago and he barley resembles his picture.
