Very common in aerospace. No particular name other than circular. Try AMP and Amphenol. They both make these. They can be high dollar or sometimes fairly reasonable. Pins require a rather expensive crimp tool usually.

Doesn't look right to me- each pin should have a letter identifier.... A, B, C... then a,b,c etc Further, the same pin arrangement can be confounded by numerous different 'lock slot' positions around the periphery.... making part numbers a nightmare.... I'd say it definitely wasn't 'mil spec'.
No way. Companies that have gov contracts to make avionics gear do NOT buy sub standard parts.
Also, don't want too much gold plating on the pins, so maybe cheap chinese is better there.
There was a time when the big guys were plating too thick and gold embrittlement issues were a problem. Now, A proper assembly has pin cups tinned and then evacuated and tinned again to get rid of excess gold from the pin cup surface as embrittlement is a real problem. A very labor intensive process. But if you did not want your contracts cancelled for shoddy cables that fail in the filed, you made sure each pin was evacuated twice.
Gold Intermetallic Embrittlement is still a real problem anywhere it is not addressed in a situation where vibration and flexure is encountered at or near a connection.

Not really. Numerics are used all the time as well. And it IS numbered. Pin 1 is identified and the trace trail direction around to pin ten and on to the last pin at pin 12.
Quite common, actually. The wires that go into the connector are many times if not all times identified at both ends with tags.
They are not "lock slots". They are key slots, and the connector is termed as 'keyed' and the reason is so that a pile of cables with similar diameter connectors can be attached and be confident that attachment to the target jack only occurs. Not a nightmare, and definitely 100% mil spec for that reason.
The Mids tray alone has several conectors on it, and ALL are 'keyed'. There is one on every jet we fly.

I am certain the US makers plate the pins themselves heavy, and the ends and solder cups lighter now.
The practice and regimen still remains, however, as an assembler does not know what pins are provided. It likely doubles solder-up time when preforming a cable build.
Still, cables of that nature are all hand built and an extra 10% labor is not all that much.
I have seen COAX cables that are $5k each because of their high end RF characteristics. And that is only two conductors! It was (is) a high end satellite cable though for a C-130 hatch installation. Pretty sure that they have them all fitted out by now.
