@WooShell@chaosfurs.social this is what Claude tells me: The alphabetic pin-lettering (skipping easily-confused letters like I and O) combined with the bayonet coupling and blue dielectric insert is a strong signature of a MIL-spec style circular connector — this family (often seen as MIL-DTL-26482 / "MS" series, or equivalent commercial versions from Amphenol, Souriau, ITT Cannon, Fischer, or Tuchel) is very common on vintage test gear, avionics, and lab/medical instruments from roughly the 1960s–90s.
