Sorry to disappoint, but this tuba was received in perfect condition, and was acquired from an excellent tuba repairman who knows how to pack and ship a tuba the right way.
And the tuba is...
a rotary B&S PT6.
It's an early handmade version, s/n dates it to 1993. A few modifications made to it, and it is in excellent overall condition. I've only played it for an hour or so, but have nothing negative to say about it, it's a wonderful tuba. Keeps all the positive aspects of the PT7, and addresses the few things that forced me to sell it.
Intonation, sound, size, ergonomics, etc. are all great... truly hoping and planning for this one to stay here for a long time.
