I found this on Ebay by that miracle of modern science, Google.

Here is a link that might be useful: Trouvailles Chippendale Black Lacquered Breakfront Item condition:

Thanks for your reply. I did see that posting. How do they know what to sell a piece for? Do I just start with furniture appraisers in the phone book?

I would do some looking o n he web...in case you don't know, Trouvailles is a furniture company dedicated to making fine reproductions of very fine antique pieces. David Israel an authority on antique furniture started the company.
I would google around and look for other Trouvailles pieces and see if you can find a general idea of price and better yet a place to advertise your cabinet.
The company has only been making furniture since some time after WW II, so it's not old....but I am sure very VERY nice!
Must you sell it?

Geez, I have never heard of a Trouvailles cabinet, thanks. And it is gorgeous.
