Swartchild & Co. Black Shield Mainspring #4395A for 18s N.Y. Standard movements, Factory No. 2190, steel, new in envelope. See images for further details. I likely have several of these so the on you get may differ slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a barely adequate job of representing the item.
