Extremely Rare 1937 Emerson AU-190 Red Catalin Tombstone Radio. The much sought after models were originally introduced in five colors, white, green brown, blue and red with red being the rarest of the colors. Catalin shrinkage was common which caused many of the cabinets to crack so many were discarded. This one has one very small chip on the top back corner otherwise it is all original and in excellent condition.
