I received a family heirloom mause r 98k that was supposed to have been brought back from the battlefields by my great grandfather after he took it off a German. I was trying to clean the bolt as the gun hasn't been taken care of in years and failed to turn the safety up before turning the rear counter clock wise. Now it seems to be setting in a grove and I can not turn it either way, even when pushing on the pin. I also failed to cock the firing pin back. So it is visible. Any way to fix this bolt or did I take it out of commission.
