Ludwig Top Hat & Cane "Swing Sensation" drum kit - manufactured in April 1941. Scarcity of metal during World War 2 limited production to a very small number. It was considered at the time to be the absolute pinnacle of the drum set industry. The best that money could buy! To date only 12 of these sets are known to exist in the entire world. The set is considered by many collectors to be one of the rarest drum sets ever produced.
