T courtesyhank you for all your replies, and apologies taking so long in replying.

I am working on a book about stand off weapons, and so I am particularly interested in variants on the Low Altitude Bomber, because this was the first project for which a stand-off weapon (Red Cat) was proposed. There is no one definitive version of the missile, but lots of differing ideas. The origins of Blue Steel can clearly be seen from some of these proposals.

I am hoping I can find the archive so that I can find out more about the intended missile.
