1936 British Metal Corporation sold its shareholding to Anglo-French Trust which was followed by a capital reorganisation allowing shareholders to subscribe for more shares and gace the company capacity to borrow money in future; turnover increased substantially with the increase in shipbuilding so expansion was likely to be needed; demand for Oilite bearings was likely to increase[7].
