[GreenKeys] Not mine, but interesting perforator.

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

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.
