John Pollard Seddon for Seddon and Co. Three pairs or a set of six oak Gothic chairs

I now have three pairs available or a set of six oak Gothic chairs designed by John Pollard Seddon and made by his family firm Thomas Seddon (Seddon and Co) who were in Bond Street and supplied furniture to Windsor castle and Buckingham Palace, founded by his Great Grandfather George Seddon. He exhibited an almost identical armchair on the Morris, Marshall, Faulkner and Co stand at the 1862 International Exhibition, illustrated in JEREMY COOPERS Victorian and Edwardian Furniture and Interiors, page 104 illustration 220 (the original drawing) and 227 (a variation of this chair) and another version is also illustrated in Nineteenth Century Design by Charlotte Gere and Michael Whiteway, page 84 illustration pl 83 (last 2 images). Circa 1860's. Seddon's partner at one point was E.W.Godwin a friend of the Pre-Raphaelites and some of his pupils were Ford Maddox Brown, C.F.A.Voysey and Daniel Gabriel Rossetti. There is a number stamped to the upper leg '3172' of these chairs and '5007' stamped on the pair below which may suggest that this pair are earlier.
