PS.
The 20K in this catalog is a 4 valve low pitch Giant Eb bell-up style sousaphone! Note that in this period, upright bells on sousaphones had different collar arrangements than on the modern style forward bell sousaphones and one could not put a forward bell on an upright bell sousaphone or vice versa.
