This might help.
I have an adapter almost like yours.
Model G-140 made by Precision Apparatus
Mine doesn't have any switches but a plug that
goes into my OLD Precision 910 tester.
That tester has also been modified with sockets for
miniature tubes. And  I have all the setting documentation
for it. I never found the full manual for the 910.
Coletronics  was a source for some of my material but they
don't list any adapters . Likely defunct now.
There is another company that might be related;
Paco-Precision  might be a successor firm.
