Sandsteel Mainspring for Waltham 12s Colonial “C” No. 2252 - Steel

Sandsteel Mainspring for Waltham 12s Colonial “C” Movements, Factory No. 2252, steel, new envelope. See image for specifications and further details. 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.
