Waltham Factory Mainspring for 16s 1945 Model No. 2247 - Steel

Waltham Mainspring for 16s Model 1945 movements, Factory No. 2247, steel, new in envelope. This spring was available in several different strengths and the ones I can supply should be shown in the drop-down lost. I likely have several of these so the one you get may differ slightly from 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.
