After converting its production to supplying troops during World War I, Arnott's resumed its growth in the inter-war period, launching such successful products as the Adora Cream Wafer and the Orange Slice, both launched in 1922, and the Monte Carlo, introduced in 1926. By the end of the 1920s, the company boasted some 150 biscuit varieties which it delivered to an ever-widening circle of customers with the company's own fleet of 19 Albion trucks.
