No. 873 was marked . MASTER RIM TOOL
I have owned 7-8 rim spreaders over the years, out of that number 3 had no markings at all ,
they were all 3 the same and were for small diameter rims ( cheap car )
Most of the makers can't get enough fancy wording on them , maybe the more it says , the more they charge?
In the day , they were a nice tool to own if you did your own tire work , like most auto owners did.
