I know NET&T bought 8-day clocks from Waltham, so I guess that this type was not available. They are all made by C.L. Guinand in Locle Switzerland. The NET&T ones are stamped "WE" in ink, so I wonder if they were distributed through Western Electric. They do not appear in any of the catalogs. Other than these three, the only other telco marked example I've seen is one from the
Wisconsin Tel. Co. Traffic Dept. These are also called "Industrial" timers and appear fairly regularly on eBay without telco markings.
