Case manufacturer?

Can anyone identify the manufacturer of my tenor case? I bought it online about 10 years ago and it has no markings on it whatsoever. It has a soft, cushioned exterior but protects the horn like a hard case. The case is held closed by a zipper, which may not be apparent from the picture.

I want to replace the strap and it has unique strap connectors, which is why I'm trying to locate the manufacturer.
