The following information is quite interesting concerning the cfm56....so I thought I would share it.
The Test Model was made in the mid 70's, and the the last "true" B707 built was cn 21956/941, first flown on 27 November 1979. It started life as the sole B707-700 with CFM56 engines in the 70's, used by Boeing as a testbed in Seattle. It was converted to become a "normal" B707-300C, namely B707-3W6C CN-ANR of the Moroccon Government, delivery date 10 March 1982. This model is a rare and great find!

Model of Boeing 707-500 and 707-700 located at the Boeing Archives Bellevue, Washington.

During the late 1960s, Boeing considered a long-range stretch Boeing 707. The 707-500, would have had the fuselage lengthened by 200in, 510cm enabling another five seat rows to be installed. This would raise passenger capacity to 225. The 707-500 would probably have been powered by refanned JT3Ds. It never went into production.

Model of Boeing 707-820 located at the Boeing Archives Bellevue, Washington.

During the mid 1960s, Boeing considered two stretched Boeing 707s. The two 707-820 versions were the 505 with a 45ft longer fuselage than the 707-320B, and the 55ft longer 506. Both would be powered by 22,5001b thrust Pratt & Whitney JT3D-15 turbofans and have the same bigger wing area, by root extensions which add nearly10ft to the span.

Probably not the place for this but a short article of a Russian review of the 707.

Damn! I wish that I had seen this back in 1958 in time to invest in Tupolev stock.

Thank you Joncarrfarrelly for sharing!
Is there more information available on Moddel 473-19 project, such as a date?
Thanks in advance.

This is really more of a secret paint job than a project - hopefully it's of interest. Recently listed Pan Am print on eBay shows an interesting variation on their classic Jet Clipper livery. The sky blue looks the same (although with a 60 year old lithograph, who knows?) but the tail colors are inverted, with the globe in white on a blue background and the cheatline tapers down under and glareshield rather than stopping at the windscreen. I doubt if this livery made it onto an actual aircraft and think PAA wound up making the right choice. s-l1600a.jpg

Another early variation on the Pan Am Jet Clipper livery. This model recently sold on eBay has the ultimately selected blue globe but retains the blue cheatline sweeping below the glare shield rather than stopping at the cockpit windscreen.
