Old Benchends
In the nave have tracery of shields and floral borders.
In chancel seats are said to be the gift of Ralph Clies, a master smith, (and were probably originally part of a rood screen) whom we see with his wife among carving symbolical of his trade-hammer , pinchers, nails and horseshoe, bellows and anvil, ladle, trammers, and cleft.
Two stall ends with figures of Andrew and Peter have fine poppy heads of an angle at a desk, and kneeling figures holding shields with the arms (three pine apples impaling an arrow-head) and name of John Peyn.
There are still more fine bench-ends in the pulpit and in a seat in the chapel.
Modern craftsman in wood and alabaster have given their best in the chancel, and the oak screen to the chapel.
