Update…
The person I saw was extremely knowledgeable about antiques in general. After viewing his inventory while waiting a few minutes, I was impressed that he was impressed with my cabinet. He thought it was of exceptional form and made between 1816 and 1820 (NY). He said he hasn’t ever seen anything of its kind and that it was likely a pair. He told me the drawers were secondary cherry (pic below) and thought that was unusual -- other parts poplar of course. Also, he was unsure about the ring under the base (pic) and thought that was different/unusual too. He confirmed that the mounts had been fire gilded and told me the feet had gold leafs although painted/stained now (pic). He did not see any indication that the doors were not original. I actually had no idea the grill inserts were brass, since they were not gilded and very tarnished.
