Allo,
could be a cartridge ''stuck'' in chamber........ if you can not find information from family members,. ask a friend who is familiar with rifles or you may need a gunsmith...$$$$$

Someone may have tried to close bolt on wrong cartridge and forced it to close..:..
handle it like it is LOADED until you get the bolt out.

very nice rifle,keep us informed on what happens.

Just saw the photos......too bad,they are great rifles......the parts like the stock,sights and even the various screws are worth money to people who still shoot the P.M. They are still used in SOUTH AFRICA by quite a few shooters...
