Some more information to answer my question. A,S.Walker's book 'Flags and banners of the third Reich', page 124, this gives you an idea of the layout but remove the black swastika and radial rings. The wing on the plate are of curved design similar to luftwaffe. The detail on page 124 is from an organsation 'DLV', (Deutsche Luftsportsverband - German airsports organisation). An organisation hardly big enough to warrent its own canteenware?.
Thanks in advance,
