BOEING 744 Aviation Parts list page 1

B744 is not a separate or different model of Boeing rather it is just an abbreviation for B747-400. B747-100 and -200 models. In aircraft jargon, the last number denotes the series no. B733 is a B737-300, B734. There are also B741& B742 B743 & B744 which are just the series 100,200,300 &400 of B747

The reason is that the -400 is a larger (wingspan etc) than earlier models so different abbreviation was needed for use on flight plans and other ATC data to let air traffic controllers realize that they are dealing with a bigger airplane. Other airlines is also using the abbreviation or code in their fleet lists and in-flight magazines.
