Original Herbert Richter (HR Design) HR 750 Car Altimeter / Auto-Barometer, made in Germany, dating from the 1970s–1980s and preserved in exceptional New Old Stock (NOS) condition. This precision analog instrument combines a mechanical altimeter and barometer in one compact unit. Designed as a universal magnetic dashboard accessory, it can also be used as a portable altimeter for hiking and mountain excursions. The instrument has been tested and is fully functional.
