Detailed history required - Can you help with expanding the wikia ? The company was descended from the agricultural engineering firm of P. & H. P. Gibbons run by Henry & Phillip Gibbons. In the late 1800s the Gibbons brothers decided it was time to make their own engines for their threshing machines and so enter the steam engine market. The development of the firm, therefore, lay in the manufacture of steam engines, threshing machines and associated equipment for the increased mechanization of farms that was taking place in the area. These were what the firm concentrated on for home and export sales. Besides these, the production of ploughs, harrows and other products became of minor importance.
