Help please finding a case....

[Pneumatic Subwoofer]

Greetings from the basement.

I'm having trouble locating a case for my tuba.

Perhaps the size is a factor as none of the standard issue cases would appear to fit.

Does anyone here know where I can find a case (preferably hard-plastic, wheeled) for my tuba?

Instrument is 28" wide, 48" tall with a 24" bell. (Martin Mammoth)

Appreciate any leads. Thanks
