FYI The CZ75 (not CZ75B) in the early 80s was bringing a very big premium ($400-$500?) in the USA, if, you could get one.
The first time a saw a CZ-75 was at a gun show in about 1989. It was right next to a Walther P88. The P88 was 1,200. The CZ-75 was 1,300.
About 4 or 5 years later when importation became common CZ-75s were about $400.
