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 one that you're dealing with?

Here's some more information that might help..

If you can't find the A.C. cord, it appears the unit will operate from 12 v.d.c. also..

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

Wavetek 131A
Sorry, I should have said it is a Wavetek 131A like this WAVETEK 131A INSTRUCTION MANUAL Pdf Download.

I found a post that says it is a NEMA type of moulded connector used a lot by HP in the 60s and 70s. Quite unusual in the UK but I worked for a US firm and they shipped gear over to us.
Also, there is one listed on ebay here WAVETEK 131A VCG Voltage Controlled Signal Generator | eBay and it shows the connector.
Yes, that looks like it, thanks a lot. Is the type an Alpha or is that the maker? It's a shame that it is out of stock.
I suspect Alpha is Alpha Wire and Cable. There are probably other vintage equipment places, maybe one of the huge rental companies has extras.
EDIT - TacPower makes a replacement (not as cheap).

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.)
