I don't know too much about this Tuba, I am selling it for a family member. It has a serial number of 339363 which indicates its made in 1954-1955. It's 29 inches high and the bell is 22 inches wide. I don't know the key this Tuba plays in,Bb Eb etc. The Tuba has four valves and It has dents dings and scratches.It has four valves and they all move pretty well. Think it a good candidate for a restoration. The bell has King HN White Cleveland Ohio etched on it. The tuba is really tarnished and all the slides move and come off. I tried to document the tuba the best I could with pictures. I'll answer any questions I can about it. If you live in the area you're welcome to pick it up. I figure I will have to send the tuba in two boxes. Sorry the Tuba does not have a case or mouthpiece.It looks like the tuba may have been repaired once where the tube from the mouthpiece attaches to the tuba body (see pictures).
