This old wrench is 16 3/4 inches long. DOE 1 1/4 inches on both ends.
No idea who made it, but it is a cool wrench!

I don't come up with anything for the number, but the shape and opening size lead me to guess tie-rod wrench....
Definitly a neat shape...
Sweet, I can't id the maker but can id the wrench type, obstruction wrench.
