As Bill states, John Oberlies made his own hardware. However, studs like the rear one were commercially available "back when", but I don't remember the manufacturer's name. I happened to see a set in the original box, but the owner would not sell them. They apparently were compatible with Winchester Super Grade swivels which were available "back when". Oberlies obviously made your front base. His handmade bases were usually compatible with the Winchester swivels. Yeah, we would like to see a picture of the whole rifle.
