This is a vintage HULL MFG. Co.of Warren Ohio auto Compass. U.S. Patent No. 1972708 Glass front piece. It seems to have a bakelite body. Some screws on the side. It seems to be pretty slow at finding the direction. A nice addition to your old 40's car. measures 3-1/2" long by 1-3/4" wide. Sort of a burgundy in color. dusty and needs a cleaning. I have had these in the past and 00 steel wool followed by a touch of armor all makes them really look great.Good Luck & happy hunting! Thanks For looking! Check out my other items !
