showing what was mentioned above

When I was shopping for my very first tuba, there was one of these available locally. Guy wanted $500 for it; it had a nice sound but was sharp in the high range and flat in the low range...one of those instuments where the low octave Eb is more like a 9th. I passed. Are all of these like this, intonation-wise?

Yes. In the early 20th century the octave was much longer than the one we are familiar with.

This would be the justly-infamous "non-Euclidian tuning" that neither Bierce nor Lovecraft dared write about, I believe?

Mary Ann,
The intonation problem could be caused by many possibilities including a mouthpiece that doesn't match up with the horn.
And, for the record, I much prefer Debbie Harry to the monkey.
