I saw a nice pristine looking nickel Model 10 (I think model 10) today, and a nice stainless 64. Both nice looking guns. The stainless is more matte, and brushed while the nickel looks nicer. Personally although they're beautiful, I don't care for nickeled guns because I don't like the mirror finish they show every single little mark and plus they don't seem to age well. I had one several years back, and it never flaked, but it had splotches on it that try as I might I could not fix. For me it's either blued or stainless.
