First a Boeing 720, more or less straight out of the Roden box with Braniff decals.
Out of the Roden box but with shortened fuselage, straightened wing leading edges and aftermarket JT3C engines, and with Hawkeye decals, a Qantas 707-138
Also our of the Roden box and with only the shortened fuselage and decorated with Hawkeye decals, a Qantas 707-138B
Moving on to the rotten Minicraft 707 kit here is one with aftermarket engines and, of course, Hawkeye decals, making it a Qantas 707-338C
Another Minicraft kit became something looking like a BOAC 707-436, using 26 decals
The final one will be an American 707-123 with lots of modifications. Here it is so far
