Nice find-don't believe that I have ever ran across a King wrench-maybe a offshoot of a "KingDick" english wrench???

Perhaps King Motor Car Company ...

http://en.wikipedia.org/wiki/King_(automobile)

I found one of these years ago and still have it.  I also believe it's a King Motor Car Company wrench. King existed 1911 - 1924, first in Detroit, then its last two years in Buffalo, NY.

I wish someone could prove it is a King Auto wrench as I have several. Seems to me that they are too many around to be for the King Auto Company. There was also a couple King Tractors but again no proof that they issued the King wrench.

There also seems to have been a King Drill {Manufacturing} Co,(Nebraska City,NB)
which was making cream seperators ~1901 ish....
(Nebraska City,NB)

Doesn't really look like a cream seperator wrewnch, but then, the one picture I found of King's seperator, doesn't look very much like the typical seperator (kinda looks like a bucket with a funnel welded to it ;P)

The KING DRILL (Nebr. City, Nebr) wrench is malleable iron, not steel.   

King Plow Co. Atlanta, GA is another possibility
