Emerson AU190 Cathedral 1937. One of the earliest Catalin made. The cathedral shape , Gothic-style, evokes the design of the early thirties wood cathedral or tombstone. It is one of the earliest radios made out of cast phenolic material, a form of plastic. Radios with this type of cabinet are called "Catalins", even though "Catalin" was the trade name of a cast formaldehyde resin from the "Catalin Corporation".This particular radio was made by Monsanto Chemical out of their Opalon cast resin product. Therefore a more appropriate name should be " Opalon" The subject specimen is in perfect condition. AC price from 4,500+
