Comsco Mainspring #1047 for Waltham 6½ ligne No. 2239 - Steel

Comsco Mainspring #1047 for Waltham 6½ ligne movements, Factory No. 2239, steel, new in frail or badly torn envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
