Sousaphone #1: A large instrument, probably a BBb ( horn is unable to be played due to lack of neck and bits). 26" bell;6 1/2" throat at bell; Bell is marked: "Made by Frank Holton and Co., Elkhorn, Wis.", serial # 93581; silver finish, but very tarnished.According to my reading of a caliper, the inner tubing diameter exiting the tuning slide is .82147
Sousaphone #2: A smallish (Eb?) horn, marked "Concertone" on bell; no serial # visible, only the numbers 22, 23, 24 on the 1st, 2nd, and 3rd valve casing, and the number 510 on the inner bell ring.The bell is 23 5/8th" diameter, the bell throat is 6", and the diameter of the inner tuning slide (exiting) seems to be .61780. I have never heard of a Concertone, but I am sure someone recognizes it as a stencil made by some company.
Any information on either horn--age, maker of the smaller one, desireability of either, etc. would be much appreciated. I like to know as much as possible before I list something for sale so I can fairly price it and intelligently answer all questions. Thank you all in advance!
