Westclox Wrist Watch Mainspring + Barrel - Lance & Rajah Watches

Westclox Model W2 Mainspring with attached barrel for Lance, Rajah and perhaps other Westclox Model W-2 Wrist Ben Watches from the late 1930's until the early 1940's (and perhaps beyond) distributed by Hammel, Riglander & Co in New York, O.R. #35. Will need to be cleaned and lubricated properly before use since they've been on the shelf for over 60 years. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. See image for precise characteristics. Images do a suitable job of representing the item.
