Sun Instruments 1931 Mug

Sun Electric Corporation was founded in 1931 in Chicago, Illinois, focusing on manufacturing electrical test equipment for automotive use. After the war, hot rodders were increasingly souping up their rides and a need to monitor their engines became apparent. Sun applied their history with precision testing equipment to aftermarket automotive gauges, producing some of the best gauges of all time that allowed racers to keep an eye on their engine at all times. From tachometers to oil pressure and everything in between, Sun made a gauge for it, and these original units that came out decades ago remain the holy grail of instrumentation to this very day with most of them still working like new.
