Waltham Factory Mainspring 12s Waltham Model 1894 No. 2279 / 2224A - Alloy

Waltham Factory Mainspring for 12s Model 1894, Factory No. 2279, alloy, hole end, new in envelope. This is the same as a 2224A when in steel. See images for further details. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
