After World War I, in 1919, Pomeroy left Vauxhall (he was then working on an overhead camshaft six and a V12 and the board was not interested in either of them) and moved to the United States where he worked for the Aluminum Co of America working on increasing the amount of Aluminium used in motor cars. Not just blocks pistons covers and accessories it was the car bodies that were aluminium. They were built by The American Body Company in Buffalo NY. Some of those cars were Pierce-Arrows using a Pomeroy engine and in other cases both engine and car were built by Pierce-Arrow.
