I FOUND A BETTER SET OF PHOTOS:
(Thank you GunBroker for http://www.gunbroker.com/Auction/ViewItem.aspx?Item=370490186#PIC.)
And these photos answer some questions. First, the plaque simply identifies the maker (but at least it does that) as Wm. S. Tompkins. Also, the inlaid details are characteristic of a Tompkins drum. I'm not sure about the pulls or the metal snare mechanism. Just insufficient information for me to form an opinion.
