Ladies and Gents,
Sorry for my silence - I was in Vietnam on a business trip for a few days and suffered a computer accident while there, meaning that I was out of action for some time (in case you are wondering, spilling beer over your laptop's keyboard does NOT improve its performance!).
Anyway, all is repaired now, I am back home, and I attach a colour scan at 300 dpi (compressed) of the original photo for all you Photoshop folks to play with.
MKG ... thanks for your observation - there is a thread in the Common Room entitled "Which brother is it", which poses the question as to which of the two brothers - the one standing between the ladies, or the one second from left is the same of a series of later photos of one of them. Your observation is consistent with replies posted on that thread!
All the best
Tim
