Heatly, Gresham Engineering Co. moved from Bassingbourn to a purpose-built factory in Letchworth Garden City (where I live!) in 1905, which was remarkable as Letchworth, the First Garden City, was only founded in 1903.
Both Heatly and Gresham were actively involved with First Garden City Limited (who owned the town) and the Parish Council - not to mention the local motor sport club!
