Thanks Pilgrim, alan, John, for sending me this info, now I will know what to look for if I ever come across one. Wonder if the shell and actually sold for £350 on ebay? Suppose good point to start looking is auto jumbles. I know 'AUTOSPARKS' make up wiring looms to order and have used them numerous times for other electrical parts, so will try them if ACE CLASSICS can't deliver and I happen to locate the correct headlamp shell....(and it will probably come complete with hens teeth!)
Thanks again
Howard.
