It may be a semi-custom pistol from Frankonia of Germany. Just a thought. Every time I could not identify a CZ, it has turned out to be either a Frankonia or CZ-UB Prague Custom Shop gun. Since the Prague Custom Shop didn't exist in 1993, my twisted logic makes my guess Frankonia. (Comin next week: How many angels can dance on the head of a pin?)
I have never even heard of an 85 Champion before. If it's legit, it would be worth at least what a 75 Champion fetches which is close to $900, IIRC.
