My stepfather has graciously loaned me this beautiful 30-06 CZ rifle. I've tried searching the web to find info on it to no avail. I'm pretty sure it's a mauser of some kind, but I don't know for sure. The only markings are the CZ,Brno stamp and a date stamp of 19xx. I can't find any other markings. Is the 19xx the serial number or date of manufacture? I removed the covered front sight and what looks like an original flash-hider. Any help would be greatly appreciated.
