Pictured here is a Bendix PT-13G5 Injection Carburetor.
Bendix service documentation shows that part list number 395720 was used on the Pratt&Whitney R-2800-27,-71,-75,-79 double wasp engine, and flown in
the DOUGLAS A-26 Invaders and the CURTISS C-46.
The A-26 Invader was the last aircraft designated as an "attack bomber". It
first flew in July 1942 as a replacement for the Douglas A-20 Havoc/Boston. First delivered to the 9th Air Force in Europe in November 1944.
The twin R2800 double wasp engines made the A-26 the fastest US bomber of WWII.
After the war the US Navy converted a number of them to JD-1 target tugs for Naval AA training.
The A-26 was used extensively in both the Korean and Vietnam wars.
During Vietnam a number of them flew out of Thailand. With very heavy armament and extra power they were used mostly in a Counter-Insurgency role.
July 1942 the C-46 Curtiss Commando entered service as the largest and heaviest twin-engine aircraft in the Air Corps during WWII. The Commandos were used heavily in Korea and early in Vietnam due to the fact they used the same R2800 power plant as the A-26 right down to the same carburetor.
The Pratt & Whitney R-2800 Double Wasp aircraft engine has two-rows of 18-cylinder in an air-cooled radial design. At 2,000hp it was the aerial work horse of WWII and beyond. Variations of the R2800 can be found in a wide range of aircraft:
B-26 Marauder, C-46 Commando, A-26 Invader, F4U Corsair, F6F Hellcat, F7F Tigercat, F8F Bearcat, P-47 Thunderbolt, P-61 Black Widow, along with a number of civilian models.
