This is a vintage truck tire type air pressure gauge marked "DILL PNEUMATIC TIRE GAUGE" on the exterior. It features the two different air inlets, and a nylon (off-white) gauge stick with graduations up to 128 PSI. It measures 12" long and is in nice shape, most of the chrome plating still intact, only a few small areas where the brass is showing through. We did test this gauge on a modern valve stem, and it seals on the stem just fine, but doesn't seem to gauge correctly even though the air doesn't leak through it. Will make a nice display tool in an automotive shop, or for repair if you want to use it. It is rare to find one of these made by Dill Mfg. Co.!
