Waltham ONE DIAL Watchmakers' Gage - Universal Watchmakers Gauge

Waltham ONE DIAL Watchmakers' Gage, marked Waltham Watch Co Watchmakers Gage, and Pat'd Jan.1. 1907.  Aside from the curious spelling of Gauge as Gage, this was intended to be used as somewhat of a universal gauge for sizing all things a watchmaker would need to size (including mainsprings), without the accuracy of today's vernier calipers. Was mesmerized by it when I bought it, when it last sold in the 1980's for $50. Tool is pretty good quality and still in truly outstanding condition given it's over 100 years old, I would argue museum quality. Images do an adequate job of representing the item and offers are always welcome.
