In 1920 the firm designed and built the first Gibbs Hampton Pattern Wheelbarrow, specially designed to negotiate the narrow doorways and aisles of the greenhouses in Hampton, Middlesex where flowers, especially carnations and chrysanthemums, were grown for the London markets such as Covent Garden. The wheel was under the body of the barrow so that it could carry extra weight more easily, especially when lifting long boxes of carnations. The back came down for ease of unloading and higher sides could be added if required.
