Thanks Billiegirl,
I think so too - the nose also seems quite similar and the set of the eyebrows. Difficult to say fully as the photo of the crew gives a view of him which would need to be better.
I know that even if the balance of probablility leans towards them appearing to be the same person, it isn't enough to decide that it definitely is him for my records, but as I am at a dead end for his fate after a long period of searching, any clue is a clue worth looking at.
I'm also 'too close' to the problem if you know what I mean. There's always a danger of seeing something one wants to see, rather than what may actually be there when personally involved. Hence my request for the objective views of others who have no personal tie to him.
Thanks for you input,
Regards Eliza.
