I have the entire sets, in metric and standard SAE (inch)measurement. They were a hot item back in the late 80's. The entire set was under $10 each. I assumed they were throw away but have taken care of them and still use them today.
Hi, Matthew7583. :-)
On the theory that there might be some clues in the patent listing, here it is:
https://pdfpiw.uspto.gov/.piw?PageNum=0&docid=02500835&IDKey=AB965CE400F8%0D%0A&HomeUrl=http%3A%2F%2Fpatft.uspto.gov%2Fnetahtml%2FPTO%2Fpatimg.htm
Unfortunately, no corporation name appears in the listing, only that of the inventor, and his attorney. It was patented March 14, 1950, so it must have been a fairly successful design if it was still being made in the late 1980s.
There are a number of older patents listed at the end of that patent. I'll give links to the full images here:
