Elgin Factory issue DuraPower Mainspring for 8/0s A-11 Military Hack No. 6002 - Alloy

Elgin DuraPower Factory issue Mainspring for 8/0s type A-11 Military Hack Watches, alloy, new in sealed package. These are New Old Stock mainsprings packaged in 1953 & 1954 for the US Military P/N DA-038-ORD-13972 and are equivalent in specifications to a factory 6002. I likely have several of these so the one you get may differ very 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.
