Vigor TONGUE End Clock Mainspring - 32 x 0 x 48" Long - T 410.1

Vigor Clock Mainspring, TONGUE End – Dennison 32 x 0 x 48" in Length, P/N T 410.1, steel, new in open envelope. 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 is hard to find watch & clock parts and all parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
