Comsco Mainspring #1009N for Waltham 16s Timer Factory No. 2246 - Steel

Comsco Mainspring #1009N for Waltham 16s Timer Movements, Factory No. 2246, steel, new in dirty, ripped & mangled envelope. Distributed by Burton M. Reid and Sons. See images for precise mainspring specifications and further details. I likely have several of theses 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 an adequate job of representing the item.
