This is for complete sousaphones (body, bell, and neck/bits) without a mpc.
Yamaha 411s = 28 lbs, 25.5" bell, 7.3/8" body bell collar, .728" valve bore. Selmer Signet = 18 lbs, 24.1/4" bell, 6.1/8" body bell collar, .728" valve bore. (Elkhart) Conn 14k = 21.5 lbs, 24" bell, 6.1/8" body bell collar, .734" valve bore.^ I should mention that the Yamaha has a bottom bow protection pad strapped on, the Signet has been spray painted 'silver', and the 14k has a clear coat over spotty lacquer.
Feel free to add sousas & their weight/measurements (old and new) if you have it
