A vintage solid brass pocket tire pressure gauge produced by A. Schrader's Son in Birmingham, England. The cylindrical brass body features prominent stamped maker's branding, patent markings, and a square mechanical slider bar calibrated from 10 to 50 PSI. Originally designed for early automotive, motorcycle, or bicycle use, this functional utilitarian piece reflects early 20th-century British industrial manufacturing. Dimensions: 10cm l

Good vintage condition. Numerical calibrations on the slide scale remain legible and the mechanical slide operates smoothly.
