Okay, time to splash some fuel on the fire
Here are some photos of the F 4-valve compensating Double tuba I spoke of earlier in this thread.
I didn't take a shot of the outer bow guards, but they do go under the ferule as on the disputed tuba. Note specifically the thumb ring flange, the similarity of the leadpipe brace, somewhat the receiver, the tops of the rotors, and a thousand other little things. Also, the bell reading "Alexander Mainz".
Couple notes - this was overhauled (extremely well done work!) at the King Factory decades ago when they still did that. So there's a reinforcing ferule on the main slide, and a replacement waterkey. The lacquer is King as well. And the current owner lowered the leadpipe, so that's why the lacquer is different in that area. The bore is larger than the curent model Alexs, and the bell shape is substantially different than the current model, and without a wreath. Finally it plays... well... okay. The upper Bb is grotesquely flat, and the low C is beyond difficult compared to the normal Alex.
Any thoughts?
