After more thought, if the T+X is on the lower right wing I have deliveries by aircraft type of, Fw58, He50, He51, Ju52, Ju87, Ju88, W34, Bf109, Ar66, Do18, Fw190. (If the T+X is on the lower left wing the possibilities are endless.)
 
 If the photo shows the lower right wing which is quite square/rectangular this would eliminate some of the aircraft listed above.
 One possibility could be a Ju88. You will notice the "T +X" are not spaced evenly from the balkenkreuz. I see that same arrangement on this Ju88 photo showing the left wing.
 e.g. "T +X (fuselage) O+ E"
