Help identifying a trunk.

Hello,
I am a juggler and I've been using this trunk for years. I love it. Unfortunately, it's starting to get a little weak and I was hoping to find a replacement. I've looked everywhere I can think to look...called it everything I've thought to call it, and still can't find anything similar.

Any help on where I might find another...or what to search for...or any other information would be appreciated.

Thanks in advance. Paul

(what an awesome site by the way...)
