I have an old Wavetek signal generator. I loaned it to someone and they lost the lead so I am trying to find out what the name of the plug is on the equipment end. This device is from the early 70s and had a removable mains cable, the equipment end connector is a 3-pin, the shape is oval (about 1.25 inches wide and 0.5 inches high) with three pins in a row(ish) with the centre pin slightly above the outer pins. I think the centre pin is earth. The pins are all circular. Can anyone tell me what this lead is called so I can try to track one down?

Is this the right footprint? Was your cable European on the outlet side or did you use and adapter?

For whatever reason, we always referred to those as "tape recorder cords".

I believe "Wollensak" tape recorders and projectors from ca. 1950 - 1970 used a power cord with a similar connector. Searching for, e.g., "Wollensak power cord" may turn up a usable substitute. Somebody who was associated with audio-visual (A-V) equipment in that era may have a few power cords laying around. I think the early versions of that connector were two-prong (ungrounded), and later switched to 3-prong (grounded).

(That brand was ubiquitous in U.S. schools during those years. I won't claim the power cords are interchangeable with your Wavetek generator without at least some dimensioned sketches for comparison.)
