I have a number of these NOS Stewart Warner Oil Pressure and Temp gauges.
The oil pressure gauges are the larger 2 5/8 diameter units. They have curved glass lenses and cresent needles. These gauges are brand new in the original boxes and sealed in the inner package. I removed one from the package to show what the gauges look like. all the gauges are from 1959/1960. The paint on the bezel can be removed to reveal a silver color metal that looks to be stainless steel.
These gauges are $150 each plus shipping. I will consider a package price if you want more than a couple.
The oil temp gauges are the back mount type. These are NOS, never used or installed. The capillary lines are long enough for any application you could imagine. Hot rodders like to use these gauges for water temp applications. That would be possible if you have a port that will accept the very long capillary probe. These oil temp gauges are the larger face back mount style. The face diameter is about 2 3/8 inches. The bezels are painted black and are brass underneith so they can be polished. These oil temp gauges are $250 each.
I do not have an endless supply of these NOS gauges and I plan to sell them until they are all gone. Once they are gone, there will not be any more.
