Family legend does not record what became of the gun after that, and everyone who would remember is, alas, dead. I expect either my grandma made him get rid of it on general "no firearms in a house with small children" principles, or it went back into the desk drawer and was subsequently destroyed, along with the desk, when the storage facility they'd stashed most of their possessions in while living in Australia burned down. (He worked for Standard Oil and they kept moving him around.)
