CR Mainspring for Waltham 14s Factory No. 2209 - Steel

Charles Robert Mainspring for Waltham 14s Model 1870 movement, Factory No. 2209, T-end, steel, new in replacement envelope. I likely have several of these so the one you get may differ slightly from the images. 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.
