The jaws on this wrench are not parallel:
http://home.comcast.net/~bobengelhardt/wrench.jpg
Specifically, the face of the movable jaw is perpendicular to the
"ways", but the fixed face is not. But they aren't sprung or worn that
way. It seems that it was made like that. But why? Just plain poor
quality? But that's *really* bad. It's an old wrench, not Chiwandian.
It says drop forged, if that helps.

The angle of the fixed jaw looks square to the rack slider. The
moveable jaw is definitly a few ° off, and it's not deformed that way
from stress. The quality of machining and finish on the tool
(discounting wear and tear) suggests poor factory work as the culprit.

The width of the open jaws is very wide -
I suspect the wrench is a jam on wrench.
Does look odd.

My guess is that it is a quality control escapee; either that or it has
been abused at one time or another. I cannot imagine one like that being
purpose-built.
Are you SURE that that is the original jaw??

I think it was just not a very precise wrench. I have seen this type of
thing in very old tools. I imagine that when it was made its fit was plenty
good enough to turn the big square nuts in use at the time and its strength
might have made it a "quality" tool in spite of its imprecision.
