Ingersoll Mainspring for Reliance Pocket Watch Factory No. 1365 - Steel

Ingersoll Mainspring for Reliance Pocket Watch, Factory No. 1365, steel, hole end, new in envelope. Typically measures about Dennison 11 x 1½, but the strength often tends to vary about 1/2 Dennison either way - the difference won't be an issue in an Ingersoll. Distributed by Hammel, Riglander & Co in New York, O.R. #11. Could also very well fit in other dollar watches as well. I likely have several of these so the one you get may differ slightly from the images. Images do a suitable job of representing the item.
