Re: Tenor Conn New Wonder Series II or Tenor Selmer Super Action?
The New Wonder II or Chu Berry Conn's are advertised here and elsewhere frequently. And Mom is right - can't tell you a cost without knowing the condition. I've seen them from $400 - $3000 advertised.
Your question mentioned a Selmer Super Action, aka Super Balanced Action. You would find this horn's action much less clunky than an older Conn. Also much more expensive, i.e. $2000 - $9000 perhaps. The Chu Berry horns were products of the 1920's. The SBA Selmers had improved key-work and action, along with a more ergonomic alignment. Most of these you see will be from the 1940's and early 1950's. I think they came out in 1936. The early Mark VI Selmers are supposed to be mostly like the late SBA's. Later.
