I have no direct knowledge on that particular gun, but typically, commercial renderings of military firearms are more finely finished. I would expect that the metallurgy of both, would be the same. So far as value goes - unless the military version you have, has some unusual provenance attached to it and assuming the commercial one is actually, better finished - I would think that the comercial one would be worth a bit more $
yup, only the blueing is betterMore likely that the M57s are made on the same equipment today as they were 50 years ago.
Would the newly manufactured ones have the external frame safety?
