Waltham Factory Mainspring for 18s Model 1892 # 2222 - Steel

Waltham Factory Mainspring, Factory No. 2222 for 18s Waltham Model 1892 steel, new in possibly very frail envelope. See images for further details. These were available in several different strengths and those that I can provide can be selected from the drop down list. Similarly, I likely have several of these in each strength so the you get may differ slightly from the images. 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.
