Picked up these 2 alligator wrenches for my collection. Thought they seemed unusual and very old. They are stamped "Kearney & F CO." Also found is a "K & F" logo within a circle. There is the word "trademark" also stamped. I could not find any wrench or tool company information with this name. There was a Kearney and Foot file and rasp company, but no reference to any wrenches. Any ideas would be appreciated.
