PM Mainspring CS-285 TIME for Imhof 519 Alarm / Travel Clocks

PM Packaged Material TIME side Mainspring for Imhof 519 Alarm and Travel Clocks from the 1930's and beyond, PM P/N CS-285, GR Ref 33-20 C 78, Tongue-End, steel, new in open envelope. Could also very well fit in other Travel & Alarm clocks. See 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.
