Waltham Factory Mainspring for 6s 1889 Model No. 2217 - Steel

Waltham Factory Mainspring for 6s Model 1889 Movements, Factory No. 2217, steel, new in frail envelope. See images for further details. I likely have several of these so the one you gt may differ slightly from the images. I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
