Very well cared for horn that will absolutely shine as a looker and player once completed. The one tiny thing I can find to mention is its missing one of the octave lever guides as shown in the 11th photo. Most brands don't put a guide there and it will be easily addressed when you have it overhauled.
Case is original and free of any musty odors as is the horn. Once overhauled you will have one of the great alto models ever made.
I've played Chu altos a lot, currently I play a New Wonder I and there is just something remarkable about the quality and tonal quality of these horns. Show this to your tech, they should be thrilled to have a chance to restore it. The item "1928 CONN New Wonder II Chu Berry Silver Plated Alto Sax" is in sale since Wednesday, November 6, 2019.
