The story
The company Wilson-Pilcher was founded in 1901 by Walter Gordon Wilson in London to produce automobiles. In 1904 it was acquired by Sir WG Taken Armstrong Whitworth & Co., Limited and production moved to Newcastle upon Tyne. Percy Pilcher had died in a gliding accident in 1899, and Wilson had been working with him on the engine for an attempt at powered flight. According to Bonhams there is photographic evidence of a wooden mock-up of the car in 1899, and a photo of a working car taken at Stanhope Hall in 1900.
Production stopped in 1907.
