Another photo cropped up in my searches which may be of interest -
http://www.ebay.ie/itm/RAF-TAIL-END-...item1e989bdc06
Caption RAF., TAIL END CHARLIE., c1950., original vintage photograph
I'm not an expert but this could be a Ju 90 in French marks (seller says british) but tail marks look more French to me.
Any comments?
