Cado style modular shelf system - who made this one?  

I have inherited an oak wall system that looks like the Cado systems that are normally in teak or rosewood.

I can find no identifying marks anywhere, so I am guessing it is not a real Cado...but someone must have made it and I would love to know who so I can best decide what to do with it.

I have included a close-up of the hanging device, which I think/hope can help someone identify who made this system. other images are in the link attached

Any insights into this unit's origin would be appreciated.
