Excelsior #2842 Mainspring for Imhof Alarm / Travel Clocks

Excelsior No. 2842 Mainspring for Imhof Alarm and Travel Clocks the 1930's and beyond, steel. Believe this is the ALARM side spring. Could also very well fit in other Travel & Alarm clocks. Sees images for precise mainspring specifications. 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.
