Hello Stig;
I am schoked, not recognising a standard Ju 88 D-1 when you see one?
These notes below are just an sample of how to recognise! (Just written here from memory - Not complete listings - Any comments will not be listened or responded too
What makes it an A-1F, A-5F, D-2, D-1, D-5 model? Mostly the absence of Dive-Brakes, Camera ports on underside, heater inlet scoop on top of fuselage etc. Mudguard Fences on underside beside camera windows (on bomb-bay). FuG 10 trailing-wire antenna mast moved to left side bottom an angled outwards (to be ´out of sight´ of cameras = Standard on all Ju 88 from late 1939, except the Torpedo Bombers, then straight down, f.e. the A-4 LT / A-17).
Then - A-1F (VDM metal props, short-wings, Jumo 211 B engines) Camera ports for the ´Rheinbild´ Rb 30 Cameras, Single ring (one+2gun upper-rear canopy), - A-5F (VDM metal props, long-wings on all models onwards, Jumo 211 G) Single ring rear gun etc, D-2 upgraded to Beetle-Eyed ´twin´ two-gun installation 1941 (similar as A-5 F), - D-1 (VS 11 Wood props, Jumo 211 J engines), - D-5 (VDM metal props, Jumo 211 J engines) etc. Many had the Gondola removed for more speed Longer distance Recce and had reduced crew of only three.
D-3, 4, 6, C-7 etc. were specials (often difficult to recognise).
hope you have some success using this as ´handbook´
cheers
