I took it all apart and went over it all with a magnifying glass and then an electronic microscope and found nothing. The bore mic.s at .280+/- so it could be European 7mm?
Yes it's definitely not a Triplett and Scott but what cool guns those were. It certainly could be a "home made" or more likely a locally made firearm. I do enjoy finding odd unmarked guns and then searching for books and info about them.
