I have successfully sold off excess(?) CZ surplus pistols, both on "The Original CZ Forum" and on GunBroker.
Come up with a price with which you will be happy (but you should probably PM me first on the CZ52 9x19mm one - I bet that would bring top dollar on the open market!) and list them here. If they sell, you and the buyer are both happy -OR- set that price as a minimum bid on GunBroker and see where it ends up at the end of the auction.
With the CZ Forum you might be helping a fellow enthusiast find his grail gun. With the significantly larger audience on GunBroker you might find out just what the actual value really is out in the CZ collector world.
I recently listed my last CZ52 on GunBroker
http://www.gunbroker.com/item/592699349 - it is a very nice pistol and looks good to me, but so far there are no bids on what I thought was a reasonable Starting Bid price. You just never know.
The pistols you mentioned sound like unusual and exceptional specimens to come on the market for the time in which we currently live. I for one would like to see some pictures if you can post them, just so I could have something to fall asleep dreaming about when I lay my head on the pillow after a particularly difficult day.
