Yes, they were common on desktop calculators as well as HP equipment and other
stuff in the 60's. They were something of a de-facto standard before the IEC
standard. I have several, one of them is made by Belden (-->Volex).
Searching on "Belden 7A 125V" (because that's what's stamped on the one
I have)
turns up this in the Electro-Sonic catalog:

Top of 2nd page. Connector PH-163, cordset 17280. They even elaborate on the
flipped polarisation. More searching on those may turn up more sources.
These were discussed on the list a couple of
years ago, IIRC at that
time somebody provided a reference to some place still selling them.
There was a discussion about Bulgin connectors a couple of years ago --
I think Tony provided most of the information at the time anyway. ;)

However, the HP 9125A connector isn't a Bulgin one:

It looks the same as the one on my Singer/Friden EC1118 calculator,
which probably doesn't help much. I've never seen them anywhere else; I
guess the closest thing would be an Italian inline mains socket...
