In used condition, scrapes from use, but wheels, hinges are fine. Interior is perfect. fits my King 2341 well, also accommodates taller tubas like a Miraphone 1292. Check manufacturer to confirm if it will fit your horn.
$225 plus Greyhound shipping costs- If seriously interested, I can email you a pic, but it looks like a used case.

Can this fit a pt6?

from MTS website,
Medium Frame Tuba Case 1207V

When you need a case for Tubas, MTS Products is your best choice. These cases are manufactured to withstand the rigors of "Student Abuse", and their universal design will fit 95% of all instruments. MTS designed this case to fit horns with an max length of 37" and a bell size of 20". Some of the common horns this case will fit are, St. Petersburg, Conn 2-5J along with 12J and 15J, Meinl Weston 2145 and Meinl Weston 18 to name a few.
I would check with the manufacturer to be sure, but I suspect it will.
