Set Lever Bridge for Felsa (F) 6¾ Ligne base caliber 4072 movements

ONE Genuine Swiss Material Set Lever Spring / Setting Bridge (445) for 6¾ Ligne Felsa base 4072 and variants (4172, 4177), new in sealed packaging. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.
