How accurate is the timescale for this crash? There were a lot of RAF aircraft operating over the Balkans late in the war.
Try this for a starting point. Go to the Commonwealth War Graves site search for Albania. The casualties killed over Albania are commemorated in the Tirana Park (I think that's how its spelt) memorial. With the communist take over, I think the graves were removed and there is now a communal grave or something like that. This will give you some clues and you can then search the squadron records or books like Flights of the Forgotten and my own book which I'm not allowed to mention!!!!!!
