A friend who has given me many fine wrenches over the years, gave me this one the other night. It is 12 1/2 inches long, has the number 2272 embossed on it, and has C inscribed in a diamond stamped on it. It looks, from the size of the openings
(2 5/8", 2 1/2", 1 3/8", and 2 1/4"), like a hub wrench. Can anyone identify how this wrench was used, or who made it?
