I have two to learn about. The first is a Model 31-1. It has a 4" barrel, square butt grip, 6 shot cylinder, fixed sights, and blued finish. The serial # on the grip is H27578. The caliber is 32 Smith and Wesson long. What would be an approximate age?
Second is marked 32-20 ctg. on the barrel. It has a 5" barrel, and a square butt grip. It has fixed sights, and is a six shot. The serial # on the grip is 117550. The number on the yoke/crane is 91298. It has been re-nickle plated, as the hammer and trigger are both nickle. I know that it would be a hand ejector model, but what change number and what would be an approximate year of birth for this one. Any help appreciated, thanks, Joe.
