Progress is fine, but it's gone on for too long.: Davis and Furber Machine wrench

Sizes unmarked, this must have been part of a tool kit supplied with Davis and Furber wool processing machinery for specific bolts.

The company was founded in 1832 at Andover Mass. It grew with the industry and adapted to synthetic fiber processing after WW2. A division was set up in Charlotte NC during the same period. The company was in business till 1964. Incidentally, the sizes are 5/8 and 11/16".
