Herbert recognised the potential of power driven vehicles on solid tyres and with the end of the First World War providing many redundant military vehicles, he was quick to seize the opportunity. Soon Gibbs were adapting old lorries for use on farms and for transporting goods to market, their experience of building wagon bodies being adapted to build bodies for commercial vehicles.
Lorries built and supplied by Gibbs became a regular feature at Covent Garden and other London markets, gradually replacing the horse-drawn wagons.
Gibbs also made the market desks from which farmers sold their produce. The desks were designed to fold down and lock when not in use.
