Does anybody know what are the brand and model of the following pictured swivels?
At the top of the �cylinder� is a button that when pushed releases detent ball bearings, and the sling half separates from the base bolted or screwed to the stock. An early "quick release" design. I believe these are 1920 -1940 vintage swivels. (In the butt stock picture, the swivel is missing the metal sling loop.)
Second question: when Savage catalogs listed third party add-on options (swivels, sights, mount, etc.) from the same time period, has anyone received a factory letter for a rifle that specifically names the addition?
