Kienzle tachometer, No. 266225, produced in 1969 in West Germany in cooperation with A. Rauwers. This collaboration occurred more often with measuring instruments for professional vehicles: Kienzle handled production, while Rauwers was responsible for distribution and any adaptations for the Belgian market. The device bears the number 77786, signed by a Rauwers expert on 24/09/1969. This item includes the original key, which allows the unit to be opened. The tachometer has a measuring range of 0–70 km/h and was originally used in late-1960s trucks. The speedometer is still in working order. Ideal for: • Restoration of vintage trucks • Collectors of historical vehicle gauges • Retro industrial decoration
