Enjoy the photos!
Quite few transitionals imported about mid-90's, a lot were AA imports. I have had several non-B guns marked "Model 75" but square trigger guard, pinned in front sight, ribbed slide, straight slide serrations, etc.
CZ made a lot of "non common" pistols. I had a CZ 75 non-B in .40 S&W once. It came in from Pragtrade in Ontario, Canada and was imported into the US by a policeman who submitted the import form to ATF. Lots of "experts" on here said there was no such thing so I posted pictures. hahaha I have read CZ made a run of about 250 .40 cal's sometime before they officially came out with the CZ75B in .40. Only a few went to Canada and who knows about the rest.
BTW, the matte finish was not parkerizing it was actually a matte blued finish. Still have a 91 matte blued AA import.
