Excelsior #2860 ALARM Mainspring for Imhof Model 549 Alarm / Travel Clocks

Excelsior No. 2860 Mainspring for Imhoff Model 549 Alarm and Travel Clocks the 1930's and beyond, new in envelope. This is the ALARM side mainspring in steel. Could also very well fit in other travel & Alarm clocks. See images for precise mainspring characteristics. 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.
