Hi Carl,
perhaps Stan will remember his dads Star wrench, it is possible that STAR was on his wrench.
isn't there a number on yours ????
as for patent drawings, the manufactured product is not always as the patent shows, most of the patents are for a special feature of the product.
example would be the Ellis wrench, it has the patent date on it as 03 although he never received the
pattent approval until 04.
I have a few wrenches that are not 100% of what the patent showed.
I am no expert, just trying to help, good luck, Frank
