Waltham Factory Mainspring for 14s No. 2211 - Steel

Waltham Factory Mainspring Factory No. 2211 for 14s movements, steel, new in envelope. These came in an original Waltham tin (not included). I likely have several of these so the one you get may differ very slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a marginally adequate job of representing the item.
