Look for Armstrong wrenches in the pawnshops or yard sales. At some point in time, Armstrong manufactured wrenches for Snap-on.
The ones that I have, came from the Norfolk Furd plant when it got shut down. (I made sure to fumigate them for rust mites before I let them get anywhere near my Chevys.)
They are sleek, smooth and feel good in your hand and are precision made.
