I would pay $1000 plus for a Model 70 in mint condition.
100-300 USD or so
The Puma is an alloy framed version of the Model 70, no longer marketed. Value is ABOUT $200 in very good condition. If selling to a dealer, about $100-$120.
7.65mm is .32 caliber. I own one of these guns and love it.
Made 70-82. 50-200 USD or so
I don't know of any published sn data for commercial CZ products.
You will have to call Beretta to find out.
There is no such vehicle as a Ford Beretta. Chevrolet produced the Beretta, not Ford. The 1991 Chevrolet Beretta uses a 195/70-14 The Beretta GT uses a 205/60-15.
You will have to shoot as many different bullet weights and brands as you can afford. Most weapons will show a preference for one or two.
