I like the 75 line, and have owned several CZ-82s -- have had a bunch of 75s and 75bs (and still have an 85 Combat and P-07); also had a CZ-97B and a variety of "clones" (none of which really were clones, including a number of Tanfoglio-pattern guns. The rest of the CZ pistols, the older ones, are less interesting to me.
I had a CZ-50, and shot a friend's CZ-52 a good bit. I also had a VZ-52 semi-auto carbine for a while. (The pawnshop where I found it thought it was an Enfield, and had it listed that way on their books. I didn't tell them they were wrong -- as they were real snots and thought they new everything about the gun. (A semi-auto Enfield?) The VZ-52 is an interesting, simple design. Never shot it... couldn't find a good place to shoot it, and ammo was hard to find at that time.
Yeah I owned a CZ52 at one time. It was a bit of a novelty gun but ammo became scarce so I sold it. It was a blast literally and figuratively to shoot.
