It;s a shame the picture is reversed. In real life it was on its port wingtip.
When I lived at RAF Aldergrove in the late forties I used to crawl around a Sunderland that was in the aircraft dump with various Lancasters and Halifaxs. How it got there I do not know; the road from Lough Neagh was impossibly narrow including a steep hump backed railway bridge; so it was possible that it landed on tha concrete at Aldergrove for some reason.
I had this idea of converting one of the floats to a boat but the RAF police kept chasing me off the site.
