Must be solid gold blades and contacts, not just gold plated!

By golly the adapter is still in the Hubbell catalog,   HBL5289. They even call it crow foot to NEMA 5-15R adapter.

You've reminded me of a situation at a former employer.  They had used that 3 pin DC connector like our current U ground AC connector.  The electrical maintenance guys referred to it as a crowfoot. This was a facility that was built in 1908.  Even parts of the campus built in the fifties had these receptacles. The company stock room "sold" a lot of adapters between the newer grounding AC connector and the crowfoot.  I think the adapter was a standard Hubbell offering.  I wonder if they still list it.

I always wondered if this was used in other industrial facilities as an AC connector and if so why Teletype used it for DC.

have a big power supply to lug along.

Looks like one of those three bent blade connectors on the cord.

So I'm guessing it has to have an eternal supply. \'/
