Abelheira Paper Mills Limited

A large number of Grahams companies, registered in Glasgow, were trading individually in Glasgow and elsewhere, including Portugal and India, as early as the late 18th century. Grahams Trading Company Limited, however, was incorporated on 29 July 1924, as general merchants and manufacturers all over the world, with a registered office at 7 St Helen's Place, EC3. It was an amalgamation of several of the older Grahams companies and the newly acquired "Portuguese companies". The latter, Abelheira Paper Mills Limited, Boa Vista Spinning and Weaving Company Limited and Braco de Prata Printing Company Limited, had all begun in the late 19th century and were registered in Glasgow but traded in Portugal through William Graham and Company, William and John Graham and Company, and William Graham Junior and Company, who acted as their agents and held title to the real estate in Portugal.

The Portuguese business of Grahams Trading Company Limited was held through West European Industries Limited. In 1947, the "Portuguese companies" went into voluntary liquidation, and the various mills and factories were gradually closed down and sold off in the 1950s. Grahams Trading Company Limited was taken over by Camp Bird Limited in 1957 and went into voluntary liquidation in 1960.
