Kent O Adjustable Speed Wrench Rare!
This is a very rare, nice clean antique adjustable speed wrench marked "KENT O" on the main bar of the wrench. The mark is light, but the letter can be seen, plus I have seen others with a deeper stamp. This wrench allows the user to move the jaw into place quickly by releasing the gear driven jaw section with a turn of the handle, next simply turn the handle back to re-engage the gears, then tighten to the nut. There is also another stamp on the moving jaw "$2.50 MADE IN U.S.A. PAT. PEND.". As you can see some of the nickel plating has come off, about 50% is still intact, otherwise this wrench is in A+ condtiion, no dings, jaws and bar very straight and nice, little sign of use! A very unique wrench!
