In return for a modest donation - which I'll leave up to the recipient - to either the Bomber Command Memorial Fund or the Battle of Britain equivalent, my new and unused ASA E6-B flight computer (whizz wheel) is available to anyone who wants it. Maybe a student will give it a comfortable home.
In addition, I have a Casio FX-730P handheld electronic computer, complete with instructions, which is programed to solve the triangle of velocities just as fast as you can press the buttons. I'll first change the batteries to check still in working order. The donation condition applies.
Hope the mods don't object.
