My Pre-Bs
1985 CZ 75 (edited had year as 84 it is 85) - Picked up last month - I believe it has not been fired since the factory. Looks to still have factory grease on it - I made the first marks on the magazine (mag that came with it will only work in this pre-B and not my other 2) and it had hardly any markings on it from racking the slide till I got it
...I'm going to clean it and take it to the range soon. The import mark is painted on, not engraved and painted.
1990 CZ 75 - no import markings
1991 CZ 85
On the two I have shot (well all 3) I have not changed any springs or anything..just the Lokgrips on the CZ 85.
