I recently inherited a VZ24 from my father, and have been researching the rifle in general. After a couple of weeks online, I still can't get a reference for the date of manufacture for this particular rifle. Serial number is XXXX O3. I take it to mean this is the third series of O manufacture (26 x 2 =52 + 14 =66 x 10K =660K + my serial number). So, anyone out there know when the 660K therough 670K of vz24 's came out of the BRNO factory. This rifle has no Czech eagle or Nazi markings on it. I appreciate any help you guys can give on this.
