Vintage Heller Bros "Masterrench" Self Adjusting Wrench Review

\In this video we look at a 1920's version of the Speedwrench.
A unique design for a self-adjusting ratcheting wrench, that can wrench at an angle.
We'll see if the claim of 45 degree wrenching is true, when I attempt to wrench around my beer.

This wrench was designed by Homer Mead & Earnest Lynch in 1921, and was sold by the Heller Bros in New Jersey.
