Howard Factory Mainspring for Howard 10s No. 796 - Steel

Genuine Howard Factory Mainspring for Howard 10s movements, Factory No. 796, Rivet (tongue) End, steel, new in wrapper. See images for further details. Aftermarket versions of the 796 were usually tongue end, not the factory rivet end. Recently came across a box of original Howard Factory mainsprings, all of them in remarkable condition given their age and considering the thin paper they were wrapped in. 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.
