Picking your brains

I'm having trouble identifying these two pieces.  The closest I've come are a picture of a Thayer Coggin sofa that's somewhat similar and a James Inc. chair that looks like it might have come from the same collection, but nothing identical.  Both were designed by Milo Baughman.  Baker maybe?

A mid-century dealer in Dallas tried to talk Joe at Atomica Modern into selling the sofa to him after I had already put down a deposit, but Joe refused.  He told Joe he could probably sell it for $3000, but he didn't identify it, and Joe didn't know its history either.

The James Inc. chair I saw had identical legs/casters and similar cushions, but the arms were a little different.

Know anything for sure?  If not, any educated guesses?
