Scale model of a Norths Navigation Collieries Coal Truck. In 1888, a syndicate headed by Colonel John T. North purchased all the colliery interests of the reconstructed but then insolvent Llynvi and Tondu Coal and Iron Company Ltd. and, in the following year, formed North’s Navigation Collieries (1889) Ltd. which deepened the Wyndham Colliery shafts to 353 yards to prove and develop the Nine Feet seam and other seams of the Lower Coal Measures.
In 1906, Messrs. Cory Brothers & Co. Ltd. bought all North’s Navigation colliery interests in the Ogmore Valley.
