Hi All,

 I have had a mooch on the web and to be honest next to nothing only one possible lead that you will have to follow up personally in below links.

( Above link you will need to scroll down to the chairs, Underneath picture  click on [ Item Details ] which more than likely will not help but have a look and see there may be another clue )
