This set of 4 models represents the Pratt & Whitney JT3C axial-flow turboject engines fit to early Boeing 707, Boeing 720 and Douglas DC-8 airliners.  The JT3C saw extensive service in airlines for many decades.
 
This set of 4 engine models includes pylons appropriate for Boeing 707-120 and 707-200 series models. The outer port engine pod pylon (engine 1) and two inner engine pod pylons (engines 2 and 3) include conspicuous engine-driven turbocompressor inlets and humps over the main engine inlet.
 
The Boeing 707 used three engine-driven turbocompressors to supply high-pressure air for cabin pressurization.  The small air inlets and associated humps are visible on the pylons above the main engine inlets of engines 1, 2, and 3.  The outer starboard engine pod pylon (engine 4) does not have a cabin pressurization compressor inlet.
 
The JT3C turbojet is the civil variant of the J57 engine used in military aircraft such as the early B-52 Stratofortress, B-57 Canberra, C-135 Stratolifter, KC-135 Stratotanker, F4D Skyray, F-8 Crusader, F-100 Super Sabre, F-101 Voodoo, F-102 Delta Dagger, A3D Skywarrior, etc..  The JT3C engine was very loud. To help reduce sound, the JT3C turbojet engine was further developed into the JT3D turbofan.
 
A set of JT3C engines with just 2 cabin air compressor inlets, suitable for Boeing 720 models, and another set without pylons, suitable for Douglas DC-8 models, will be made available separately.
