Hi,
Airfix did a kit of a 737-200 in 1:144 scale – I used to have this one a few years ago. The model comes with British Airways (Old c/s) and Air France decals. Not a bad model for an Airfix one either – more detailed than the others in the range which include a dreadful 747-100 in the same scale.
I still own some of the Airfix models that were brought out in the same line including an A300B4 and DC-10. I also own an Airfix BAC 1-11-200 in the same scale which isn’t a bad one. I’m pretty sure that the 737 model is still being sold in some places – Though it dates back to the 1980’s when they brought it out under the ‘Modern Airliners’ range. They repackaged the airliners in different boxes with differnt artwork later on. The only Revell model I own is a KLM 767-300 so I can’t be sure if they ever did a 732.
Hope this helps.
Jim.
