It is not at all interesting if it is a "real" Healey or not. What is
important that the car is functioning properly as the owner would like,
original, modified, hot-rodded or whatever.
Anyway there are probably no 100% original running/real Healeys in
existence. Other lights, oil filter, ignition, transmission,
dynamo/alternator, SS-exhaust, tyres, wheels, noise/heat suppression,
water pump, radiator, suspension bushes, shock absorbers,
induction/carburettors, cylinder head, pistons, SS-bolts&nuts etc. etc.
