Wanted: Wanted Angelo zoli semi auto shotgun

I know this is a long shot. Lol I'm looking for an injector pin for a Angelo zoli semi auto 12ga shotgun was handed down to me. I've been trying to find one. But everywhere I call they say the company went out of business In 1984 and was told to put an ad up on gunpost. Hoping somebody might have one before. I have to go to a gun Smith and have one custom-made pictures are from Google.
