Very rusty old flare gun Restoration. In this video I showed how to restore an old rusty flare gun. This flare gun was found by a metal detector on a WWII battlefield. I decided to restore this rusty gun. I removed the rust and made new parts that were missing. I hope you enjoyed my restoration video. On this channel I show how I find artifacts: @ArtifactDigger #restoration #rusty #knife #rextorer
