Waltham Factory Mainspring for 0s & 1s '82 & '87 Model No. 2216 - Steel

Waltham Factory Mainspring for 0s & 1s 1882 & 1887 Model movements, Factory No. 2216, T-end, steel, new in likely frail envelope. See images for further details. These were available in several different strengths and those I can supply are shown in the drop-down list. 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. I have several of these so the one you get may vary slightly from the image shown, which do a suitable job of representing the item.
