 The factory was ill-adapted to mass production - it produced 209 million .303 cartridges in World War I compared with 2,373 million at Kynochs, Birmingham factory - but its specialised skills made it ideal for innovation, such as the preparations of munitions for aircraft.After the war, Eley, along with other firms, became part of Explosive Trades Ltd, soon part of Nobel Industries.Many Belgians had been billeted in Edmonton as refugees and many, as elsewhere, worked in the armaments industry.
