I would also find a knowledgeable antique dealer in Wisconsin to see what a professional opinion might be, as to the style and where it was most likely be made. If you have John Landon's death date, I would look for his will. If he was a cabinet maker, his will may list his tools as part of his estate's settlement. If he died while still in business, an inventory just might point to a cabinet maker occupation. An inventory might list the furniture as part of his household , Particularly if it was considered as unique item worthy of attention or value for tax purposes on the estate. He might have been listed in a directory or newspaper as a business. A search on fultonhistory,com may yield some clues. Good luck with your search Rick Porter Finger Lakes House Histories
