Elgin Factory Mainspring for 0s No. 2328 - Steel

Elgin factory mainspring Factory No. 2328 for 0s movements, steel, new in envelope. This one is an exception to the typical Elgin DB&H as it has a HOLE end, so make sure that's what you need. See image for further details. Elgin mainsprings are typically coated in very old grease and must be cleaned before use. Not an easy size to find. 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.
