Waltham Factory Mainspring for 10 ligne Watches No. 2271 / 2229 - Alloy

Waltham Mainspring for 10 ligne movements, Factory No. 2271, alloy, new in envelope. This is the equivalent of a 2229 when in steel. My handy-dandy factory manual (which I sell) also says this is also used in some 10½ ligne movements too. These are available in a couple of different strengths and those that I can supply can be found in the drop-down list. I specialize is hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. See image for further details. Images do a pretty good job of representing the item.
