You may care to put the word Tuba in the title so that more more people searching for Conn Tubas will hit on it. Beautiful condition, BTW.

I measured the inside diameter of the removed 2nd valve slide. This turned out to be 0.75". The 0.773" or the often listed 0.775" measurement is the inside diameter of the tube where the 2nd valve slide goes into. Additionally, the Conn loyalist website lists the 20J as having a #11 or 0.750" bore. So, that is what I am using as the bore measurement. But, I want to thank you for the information, I totally appreciate your help, and I respect your knowledge of tubas and sousaphones.
