Where these common?
Neat old wrench. Forerunner of the more modern dogbone wrench, I suppose. Don't recall seeing this particular wrench.
It is a listed wrench (S289). I only found one vague reference to the maker :(
Picture of 2 variants, I don't think it is a common wrench, may be patented...

The Handee Wrench is patented. The patentee was John Sisolak of Chicago, IL, and the patent was issued on January 26, 1926. The patent number is 1,571,148.
I found mine in an old machinist's tool box at a flea market. As far as I can determine, this was the earliest of this type of wrench.
