BESTFIT Mainspring JA350 for 18s E. Howard Pocket Watches No. 55 - Alloy

BESTFIT Mainspring MS-JA350 for 18s (N size) E. Howard Old Series Pocket Watch movements, Factory No. 55, Alloy, new in envelope. See images for precise mainspring specifications. This is a discontinued model from Bestfit so you best get them while you can as there will come a time very soon when you can no longer get alloy mainsprings for these 150 year old pocket watches. I may have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
