Excelsior #2834 Mainspring for 8-Day Travel Clocks - 14 x 0 x 48

Excelsior No. 2834 Mainspring for 8-Day Clocks and Watches the 1920's and beyond, steel.  Believe this is for an 8-Day travel clock. Measures a Dennison 14 x 0 x 48 - see images for further information. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find parts so I usually have whatever you might need and all parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
