Waltham Factory Mainspring for 16s Midel 1872 Factory No. 2208 - Steel

Waltham Mainspring for 16s Model 1872 movements, Factory No. 2208, steel, new likely an exceedingly frail in envelope. See images for further details. These came in a couple different strengths and those that I can provide can be selected from the drop-down list. An as such, I likely have several of these in each strength so the one you get may differ slightly from the images. Some of these mainspring may have been on the shelf for quite a few years but I inspect all these steel mainsprings carefully before I list them, and I guarantee them unconditionally. Images do a pretty good job of representing the item.
