Myfriends at Builderscience have just completed my latest two desk model Boeing SSTs in about 1-300 scale.
The first model is the Boeing 733 wearing Qantas colours.
The second is the Boeing 2707 wearing Air France colours.
Although there was no real Boeing SST built, Boeing presented the optionholding airlines with models made by Pacific Miniatures in the colours of the airline at the time in the 60s. My replicas are in the spirit of the models given to airline execs in the 60s and so are not especially detailed but capture the "Mad Men" era well.
