Waltham Factory Mainspring for 6/0 C 1945 Model No. 2248 - Steel

Waltham Mainspring for 6/0 C Model 1945 movements, Factory No. 2248, steel, new in envelope. These were available in a couple of different strengths and those that I can supply are shown in the drop-down list. I also likely have several of these so the one you receive may be slightly different than what is shown in the images. Mainsprings have often been on the shelf for 50 years or more but I inspect all these old steel mainsprings carefully before I list them, and I guarantee them unconditionally. See images for further details. Images do a pretty good job of representing the item.
