I am looking for the phone number to a company called King Seely. They
produce hydrostatic fluid. I believe they are located in Michigan.

I cannot be certain that this is the company you need, but here's some
information that might be useful.

"King Seeley was originally a maker of  automobile
instruments--speedometers, oil pressure gauges, etc. They supplied
these to one or more of the major Detroit car manufacturers. I don't
think they were the original makers of Thermos bottles; they must have
bought the company or the name along with some machine tool
manufacturer during the era of the Great Conglomeration. A quick check
reveals that the company is now King Seeley Thermos, and has long
since moved from Ann Arbor, Michigan to Winchester, Massachusetts."
