An old ham radio set I picked up years ago. The company's founder, Oscar Hammarlund, was born in Sweden, but emigrated to the US and ended up working for Elisha Gray, co-inventor of the telphone, and his National Teleautograph Company, whose purpose was to transmit writing over wires. (The company would eventually become part of Xerox.) In the process, Hammarlund invented what is now known as the mechanical pencil. He started his own company in 1910, and produced radio sets for decades. Although he died in 1945, the company soldiered on, but eventually the factory was closed in the early 70's. (The Hazeltine Corporation was most famous as a designer and manufacturer of WWII "Identification Friend or For" (IFF) military detection and identification systems. The Radio Corporation of America--or RCA--developed the 8-track cassette.) A lot of history in one radio set!
