Excelsior #2897 Mainspring for Alarm / Travel Clocks - 28 x 2 x 48

Excelsior No. 2897 Mainspring for Alarm and Travel Clocks the 1930's and beyond, steel. Made for 8 day clocks, this could also fit in other types of clocks (and perhaps even some 8 day watches) as well. Note while the mainspring is new the envelope has been handled quite a bit over the years. Measures a Dennison 28 x 2 x 48 - See images for further information. 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.
