At the suggestion of a fellow template maker, I decided to post some of the templates I've made here. I've attached 6 templates:
The first, the Boeing 377, was made entirely from scratch
The 720 and 707 are really just modifications of the available 707-120B template, with the engines being switched for the original JT3Cs, as well as adding a shorter vertical stabiliser. With the 720, I decided to start from scratch, shortening the original -120B, as well as incorporating the JT3Cs, and the shorter pylons on engines 1 and 4.
The L-749 is a modified L-1049 template, changing the cockpit window, engines, windows, and shrinking the tail fins. All I really did for the L-1649A was change the wing.
The Comet was modified from the Caravelle, but a lot of it was done from scratch
