Has anyone ever heard of them? I've searched and can't find any information on them. My Dad bought an over/under new in 71 or 72, he doesn't remember exactly. The gun has JBL Arms on the barrel, it has Italian proof house marks. But I can't seem to find out who made the gun. It was made in 1971 according to the stamps. It's a 12 ga. Any help would be greatly appreciated.
