Waltham Factory Mainspring for 16s Waltham Pocket Watches 2267 - Alloy

Waltham Factory Mainspring for 16s Waltham Model 1899 movements, specifically the Vanguard, Factory No. 2267, alloy, new in envelope. Same mainspring as the steel 2227. I likely have several of these so the one you get may differ slightly from the images. See images for further details. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
