A bit of a puzzle between blue (RAF) and khaki (army). Donald Sydney Davis GREEN is still in the services in Germany in 1946 and is a clerk administrating demobilisation whilst also anticipating his own within a couple of months (letters home). Writing to his parents on 11 Aug 1946 he says "we have been dished out the blue again for our best dress. At the moment we have no blue shirts or collars - typical RAF organisation - so we are holding on to our khaki until some shirts turn up. It will seem quite strange wearing blue again after all this time ..... I am not looking forward to polishing all the buttons again - that's the big blessing of khaki". There is one photo of a man in army uniform signed "Don" on the back (the signature matches all his letters home) .... but what's all this about the blue shirts ? Was he army or RAF ?
