Willis Henry, the nations best house for Shaker stuff, is having his annual Thanksgiving auction of everything it seems but shaker, lol. Included are 2 pieces which claim to be Belter, a chair & setee. I dont know if it is or isnt but sometimes one can pick up a good buy from a house that normally carries a totally different style of furniture. I did that earlier this year when i won a really fine shaker piece at Neal Auction, a house that usually handles Victorian stuff.
