I am looking at what has been described as an "S&W Military and Police Pre Model 10 .38 special 4".........
I would rate it as at least a 98% gun, maybe more.........were any of these available with a Hump Back hammer, because this one looks like it has one........I've asked if the diamond stocks are matching..............S 919124............
Someone with greater knowledge will post I'm sure, but I'm thinking it was introduced as the Military & Police and was later given the Model 10 designation?
