Elgin Factory Mainspring for 11½ ligne AS 1194 No. 6703 - Alloy

Elgin  Factory Mainspring for 11½ ligne movements, Factory No. 6703, automatic (tongue) end, alloy, new in envelope. I don't see an Elgin grade that's based on the AS 1194 but there must have been one. See images for further details and precise mainspring specifications. 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
