(just to close this thread) So according the parts manual the brake handle came from Ford, and almost certainly English Ford (Steve's find of the early Capri, and also at least on 1963 Ford Cortina (see pic)). It was used later also on at least Lotus (Elan and Europa S1, Nate's discovery). Elan S2 had a Lucas switch incorporated into the handle (and at least a few early Mangustas and Maybe the Bordinath car did have a brake light on the dash).
