Conn New Wonder Series I Bass
Date: 1923. Owner unknown
All "New Wonder" Saxophones after 1917 had rolled-tone-holes. Conn also made bass saxophones as stencils for both Selmer and Holton in 1921 and 1923 (at least), respectively (and probably longer). My guess is that these are all the same instrument, except the stencils might not have had rolled tone holes.
