Double Bass Hard or Travel Case for Carruther's EUB

[BHBassman]

I have a Curruther's EUB, has a vinyl zip up case.
I'd love to get a hard case. Cylinder(?!)
Dimensions for the case:just under 5'length, 8 inches round
Any suggestions?

Thanks-Been looking.
Even thought of an ABS plumber's tube. No luck yet.
