Between Pratt & Whitney and numerous licensed companies, there were over 180,000 of these engines manufactured in a number of specifications. The B-24 Liberator would have been their major recipient but other famous aircraft using the same engine were the Consolidated Catalina flying boat and the Douglas DC3/C47/Dakota. Refer Wikipedia link for other aircraft that used this engine.As a result of the significant and ongoing usage of these engines in civil aircraft such as the Douglas DC3, they are by no means rare. Many parts can still be sourced new and there are several companies that have the capacity to rebuild these engines to an airworthy standard.The Pratt & Whitney R 1830 is a double row 14 cylinder air cooled radial engine with a capacity of 1830 cubic inches (30 litres), developing some 1200 horsepower at a maximum 2700 rpm.radial engine, twin wasp, r1830

This engine was a Commonwealth Aircraft Corporation (CAC) build, and had been upgraded to 92 specification at some time. This engine as acquired, was completely seized and great difficulty was encountered in dismantling it. The pistons in Nos 1, 13, 3, 2 and 5 had "grown" into the cylinder bores requiring some unorthodox methods to remove them. The cylinder barrels have been brought up to a reasonable standard, those beyond repair were replaced from stock. After getting various parts from the US, this engine was eventually brought up to running order.The Pratt & Whitney R 1830 is a double row 14 cylinder air cooled radial engine with a capacity of 1830 cubic inches, (30 litres), developing some 1200 horsepower at a maximum 2700 rpm.Engine Number 54828

Some 37,200 of these engines were built, major application was in the Airspeed Oxford aircraft.Seven-cylinder air cooled radial engine produced by Armstrong Siddeley (UK). Widely used in Airspeed Oxford and Avro Anson aircraft of WWII era. This example is in running order after having been rebuilt by team members from a very neglected state.A9600 8739D 790 Sradial engine

The Bristol Blenheim depicted in the painting was a British light bomber used extensively for 2 years of the Second World War. It was powered by a pair of Bristol Mercury V111 air cooled radial engines capable of developing 860 bhp. armament was a combination of Vickers, Browning and Lewis machine guns in .303 ( 7.7mm ). A 1000lb (450kg ) could be carried in the internal bomb bay in the centre section of the fuselage.
