Here's a pic of the parts that comprise the 770 headlamp assy. The bowl goes on from behind, then a mounting flange goes on front, sandwiching the cars front panel, next, the headlamp, in a chromed retaining rim and big wire clip, lastly chrome outer rim. Quite a few bits to source, same lamps were fitted to Austins, Jaguars, and probably quite a few others. I suspect the light output will be quite inferior to that of a 7 inch unit, the 770 is pre war technology, the 7 inch evolved to the halogen age and is still with us, a version is now available with plano lens, the beam formed by shaped reflector, just like the 770, technology has turned full circle.
I rather prefer the 770, the 7 inch although only slightly smaller, looks too small, my old 401 had 7 inch units cleverly mounted within 770 outer rims, better, but still not quite 'right'. 770's packing halogen bulbs FTW.
