The purple lined case came with the first Model 57 I bought. I met a fellow at a gun show here in Wyoming who I had known when I was living and working in Alaska. He had killed a grizzly with it when it charged him. Asked if he still had the gun and he said yep. Told me he was gong to sell it. So I told him I wanted it. he said he had gotten it in the case in 1966 or 67. Bought the gun, case, a couple of quick loaders and 5 boxes of factory ammo for 600 bucks. He was looking for some 4350 powder and I had sold all but one pound I was going to keep for myself. Gave it to him.. He gave me a great deal. It is a S serialed 57. The one I just got was made in 1986 I think. It is a 57-1. I am almost positive the grips are not original. The other 4 inch N frame case I have has a blue interior. I have 4 or 5 sets of target N frame grips and a couple sets of N frame magnas. K and J frame target grips also. I also have a larger S&W presentation case for a 6 or 6 1/2 inch gun. But it has no interior. and another presentation case that was given to me after an auction with blue velvet cloth interior. S&W?? Don't know. Colt Python.?? Don't really care. Just neat older items.
