Hello everyone new member here but been lurking for a long time. My question for you all is I have a mauser that I have been able to track back to an Army model C made some time before 1930 in Berlin. I'm looking for a site or forums that I can find more info on the history and such on the model C. The rifle belonged to my wifes grandfather and as far as we know it is a 7mm caliber even though there is now caliber identifacation markings on the rifle.
