RAM 3/8 drive 5/8 socket

Hey everyone. I have just this one socket. Curious about the manufacturer. Couldn't find anything online or on Alloy Artifacts. Is it US? Feels like decent quality.

Ram and Craft are made in Japan knockoffs of S-K, as far as some of their socketry goes.

Here is a 1/4" spinner I grabbed, couldn't see the name in the low light. Got it home, and under a magnifier. Thanks to @3baygarage for providing the answer in advance of me asking.
