Hi 'Sobel' . Having looked at some of his photos online again, I can see how his hair does look dark, I suspect it was because of the fashion for hair oil, I don't think he had platinum blond hair, I suspect it was dark at the roots and blond at the tips.... That's your challenge
. As I said in my earlier post, I think he must have been very striking looking in the flesh as I've yet to see any other individual described in their intel docs in such 'glowing' terms. One Canadian General went so far as to describe him as 'unbelievably handsome, he should have been a movie star'
I leave it in your capable hands !
