Conn 34J in CC - no pics yet!

Is the 34J a 6/4 tuba?

Well it's a large 5/4.
OOPS !!
I'm glad I re read that description !
I miss read his statement and thought He said this was smaller, but
this is every bit a 5/4 tuba and should be quite good if it works properly as He suggests

Based on the pictures and measurements (18 3/4" bell), I would say it is probably about the same size as the BBb Monster, or the Eb Giant, or the "Donatelli," but with a smaller bell flare
Large 4/4-Compact 5/4. Definitely not a "6/4 Grand Orchestral"
Below is a pic of the horn in question, followed by pics of comparably sized CC and Eb Conns:

I’d wager to say that this tuba was not cut, but rather lengthened from Eb. The somewhat golfclub like tuning slide and the double looped tubing after that lead me to believe this.
