Excelsior #2919 TIME Mainspring for ORIS models 430-120M Clock

Excelsior No. 2919 Mainspring for ORIS Models 430-120M Alarm and Travel Clocks the 1930's and beyond. This is the TIME side mainspring in steel. Could also very well fit in other travel & Alarm clocks. Note while the mainspring is new the envelope has been handled quite a bit over the years. See image for precise mainspring characteristics. 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.
