Hi, I ended up with a Saito steam plant that I won at auction in NY. During the weekend, I decided to start a full cleanup and restoration of the boiler which was in very dirty but good condition. After removing the flue cover, I found this spent 45 caliber cartridge hidden. I thought maybe the cartridge just fell through the stack or burner openings, but no it was too big to fall in accidentally. I preserved the untouched cartridge in a zip-lock back, who knows. The item used to belong to a famous collector out of NY who passed in July 2019. Any ideas on how to deal with this is appreciated? [ Guests cannot view attachments ]
