HMS Ganges Association

Up Snaefell 1948.
G'Day All. I got this photo at Sunday's monthly meeting from the son of Lt Edwards RNVR (both are in the shot). None of the Ganges Boys present had
seen that Rig before (any ideas on the Number??) The blow up shows the Cap Tallies as HMS Ganges or just plain HMS. Photo taken sometime in 1948
at the top of "Snaefell" Isle of Man. Maybe someone can recognise it and supply more information
Regards
Tom.
