German Kilometer Boy magnetic Miles gauge NOS

Vintage Kilometer KM Miles gauge in new old stock (nos) condition. The miles counter is in very good condition and it works perfectly. It has 4 adjustable wheels, and the last digit is a zero and cannot be adjusted. The size is about 4 x 3,7 cm. You can mount it, on a metal dashboard, with the rear magnet. Alternatively, the thin metal plate with sticker comes between the plastic dash and the magnet of the miles counter. After the tank is filled with fuel, you just roll the wheels on the counter to match with the speedometer mileage. Made in Germany.
