Gorgeous example of an early Heywood Brothers bentwood office chair with two brass medallions stating "Heywood Brothers Gardner Mass. Pat Jan 7, 1873"
Cast brass hardware, original casters and carved Victorian legs, all in excellent original condition.
Apparently it was upholstered in horsehair and leather or fabric (there's one listed on Ebay in very poor condition selling for $600) as there are no drilled holes for wicker.
Going to the local upholsterer this morning for a quote...
