well either no one knows or just ignoring

Your posting in a tucked away section. Try opening a new thread in Projects or general BS. I know personally I don't find my way to this section of the site very often. People here would be more than willing to help you Sir.(if they see your post) also try to get some close up pics. Any numbers, markings, etc. On the piston? This would help someone ID it. I'm sure it's not that your being ignored. Sorry I can't help with your question.
