A local dude has what he claims is a extremely polished stainless 59.

I know Smith never offered a 59 in stainless, but I did find this from here.

Smith & Wesson Model 59 - Wikipedia

"It was designed for the U.S. Navy as a large-capacity version of the S&W Model 39, the basis of their Mark 22 "Hush Puppy" silenced pistol. In 1965, the U.S. Navy commissioned a version of the S&W Model 39 that could take the 13-round magazine of the FN Browning HP35. In early 1970, a dozen experimental all-stainless-steel prototypes were made and were issued to Navy SEAL commandos for evaluation in the field. The firearm was not adopted. "

Could it be possible the dude really has a stainless 59?

Sure looks like nickle to me.

Nickel has a little yellow in it. I think someone chromed that 59.

That would be a Nickel model 59

Its nickel and while there are no absolutes with S&W IMO the safety lever and slide stop should be blue so perhaps a renickel....perhaps.

Thanks everyone.
