I'm sure they're not sure, but from the description (sketchy as it is) and the pictures, this is a "USA Line/Grand Rapids/Band Instrument Co" small bore tuba. Grand Rapids was owned by York, and, according to a later employee, came down the same production line.
One look should tell you that this is not a full-size tuba, but rather, the kind that was bought by small town band tubists who could not afford two tubas, and so marched with the same one.
Instead of talking to your plants, if you yelled at them would they still grow, but only to be troubled and insecure?
