You need to use a little care with the term '737 Classic' - not everyone agrees on the definition. Some consider the 'classic' to be the
737-100/200 series. But at least around Boeing, the general definition of '737 Classic' is the 737-3/4/500, while the even older
737-100/200 are referred to as the '737 Jurassic'.
