There are a lot of people who collect Maks, I'm one of them. If you spend any time over at Makarov.com you'll run into plenty. I don't collect for profit, just for the fun of it. I presently own 12 Maks, including two Norinco Model 59's. One is a "ZZ" prefix serial no., and the other is a factory '56' model with a Bxxxxx serial number, both of which are commercial pistols made for export. I've heard reports of a factory '66' model which is supposedly a military version of the Model 59. I'm always on the lookout for one of those babies, but so far I haven't run into anyone that has one. If the one you saw has a number '66' in a triangle on the frame, I'd be very interested in buying it.
