I have a blued 357 police service six and I seen a stainless steel cylinder online that is from a stainless service six. I thought that would look good on my revolver, so my question is can I buy a complete cylinder and crane to replace mine or would there be some gunsmithing involved for it to work? i'm just getting extra parts in case i ever need them, parts for these guns are drying up. the stainless cylinders are more widely available than the blue, at least that's all i can find. i've got a spare part for everything in my six except the cylinder and crane. the cylinder and crane will probably never be needed, but if i can get them at a good price i thought why not. i found a blue cylinder like new without a turn line by itself but they want $100 for just the cylinder, the stainless cylinder and crane are used but in great shape for $75.thanks for any help
