It was dad's possum killer. Now it's an heirloom, albeit with the nickel almost completely gone. An 80 year old 16 gauge single shot Belknap Nitro Hunter. They were popular in the early 20th Century as the gun-behind-the-door ready to dispatch unwelcome critters. Interestingly, modern 16 ga shot shells won't chamber because they're 1/4 inch too long. And I wouldn't risk shooting it anyhow because I want to keep my hands, arms and face. Honestly it's an eyesore, but it's family. Does anyone have any family heirloom guns from decades past?
