I've searched all the standard places, alloy artifacts, ebay ....... nuthin

I couldn't find anything on the net.  It has the look of a Japanese vehicle tool kit wrench - meaning a certain good quality.

I hadn't thought Japanese

Absolutely possible

Been a few months, looked around a bunch more, and still nada
Total mystery
