CZ Model 50 for opinions

[Rescue190]

I acquired a CZ (VZ) 50. Chambered in 7.65 mm (.32 ACP) I was not able to find any import markings on this one. Were they all brought into the USA prior to the firearms act? I understand the CZ 50 followed the CZ 27 serial numbers and started at 650,001 in 1950. The NB 50 marking on the front strap indicates it was either issued to or accepted by the armed security forces for the police and not the military. The mag has 7 holes and is not marked anywhere. Came with two mags, I am assuming are period correct. I thought it was also strange that I could not find in the BB Gun Values. Sale prices seem to be from $300 to $600 and I do not understand what is driving the value if condition is equal. I understand they are good shooters with correct ammo. I have not shot this one yet. Thoughts and opinions are appreciated.
