I had an occasion to visit with a self taught gun smith in his seventies who has worked on guns since his teens. He had a German machine gun (WWI vintage) in his shop and told me that some time during the bond drive for WWII, you could get a free disabled German machine gun with the purchase of a certain amount of war bonds. He did not get his that way. I have never heard of this and can't find anything on the internet about this. Has anyone ever heard of such a thing?
