below is matte stainless S&W model 67, note the sharpness of the stamping for the logo and lettering. now to be completely fair, it's a different manufacturer, and S&W uses a die press for the logo on the side plate and a roller press for the maker's mark on the frame. however a CZ made in the late 80's to 90's should be quite similar vs something from the 1970's that was hand-stamped for marks and they were still figuring out electroless plating (SIG Sauer for example).
below is a Colt New Police from the early 1950's (probably 51 or 52), 3rd issue. note the crispness of the stamping that's a bit soft in the middle - this is the hallmark of a die press. a punch will be pretty strong all throughout. this is not refinished, but an original Colt blue.
this is the same gun model (not same gun) that was refinished with some care taken to not mess with the rampant pony stamping. note the softness.
this is a colt 1911 plated by an aftermarket company that did a pretty good job. note the slight "halo" around the rollmarked patent info and maker's mark as they avoided these areas with too much metal work to preserve the markings.
