Old telecom Plug name? (4mm x 3-pins)
Anyone recall those old telecoms Test Leads? The ones that had 3-off 4mm pins, two spaced at 19mm plus a third earth pin ...
I want to Google a couple for my "new" 1980s AF tester - we repair local PA gear for community halls & churches and meter has 3-way skts, so where to look or what them pesky 3-ways were called would be very kind! Thank you, Dave

We knew them as 'Siemens 3-pole' and they were on a number of HP telecomms testers such as 3770A 3724A with the appropriate options.

The only phone related 3 pin plug I remember is this configuration:

Re: Old telecom Plug name? (4mm x 3-pins)
I think this might be the one in question.
We also just called them "Siemens Three Pin". Widely used in FDM and balanced audio systems. . |

Cheers, Dave

Re: Old telecom Plug name? (4mm x 3-pins)
This looks remarkably like the handset pin-out connections on my 1956 Soviet TAI-43 field telephones which were, I believe, modelled on the WWII German 'Feldsprecher' telephones. 1/2" between the closest two pins, exactly the same as a standard PO-231 audio broadcast test-tablet plug, and 1 1/4" between the outer pins.
More than mere coincidence, I think.

Re: Old telecom Plug name? (4mm x 3-pins)
I have a lot of them here in the radio shack. I use them for 13.8v DC power distribution. A couple of portable batteries have them attached as well. Chosen long before the Anderson PowerPole connectors hit the UK amateur radio scene.
