Lot 101: 1920s Boyce MotoMeter Ford Radiator Cap & Ring

Lot 101 features an original vintage 1920s–1930s Boyce MotoMeter radiator cap temperature gauge with a Ford emblem, accompanied by its metal mounting collar or trim ring. Before dashboard temperature gauges became standard, Boyce MotoMeters were mounted directly onto the vehicle's radiator cap, allowing drivers to monitor the internal thermometer fluid tube through the glass. This authentic automotive artifact offers a rare glimpse into early vehicle technology and design. Estimate: $100-$175.
