THERMO Miles KM recorder counter gas boy

Vintage THERMO miles recorder in good used condition. This miles dashboard trip counter has also a working temperature gauge. The rear is with velcro fastener but you can replace it easy with a sticker or magnet. The size is 9 cm x 4 cm. 

A must have for classic cars without fuel gauge or with imprecise gas gauge. After the tank is filled with fuel, you just roll the wheels on the gas boy counter to match with the speedometer mileage.

Made in Germany.
