Halifax MkII Bombers Numbers W1247, W1181, DT539 and W7914
Are there any photos of these particular aeroplanes? They all flew with 102 Sqn out of Pocklington in the latter part of 1942. All were piloted at one time by my relation P/O Geoffrey King 115277 that is why I am interested in these Halifaxes. How would I go about finding photos?
