"Challenge" gas tank gauge.
Made by the Boston Auto Gage Co. Boston Mass.
Screws into top of a gas tank (thread is 2"). 10" long from underside of cap to bottom. Includes two new faces, one marked from 0 to 8.5 galls (fitted), the other 0-1/4-1/2-1.
Requires new glass cutting & fitting (easy job!).
Good overall condition and should polish up real nice.
Perfect finishing touch for that Brass Era speedster!
