Just got mine here in Europe`s westernmost corner! It is absolutelly packed with excelent stuff for the Luftwaffe buffs. I would start to review the preface, and asking Dan to please ID the quad (20mm MG151?) tail turret on the top, next to the Fw 191 cabin view. To which project did it belong to? Also, on the left bottom page, I didn`t knew that the Ta 254A-1 projected nightfighter had a hood, on a B-stand, I presume facing rearwards.
The Focke-Wulf tail turret is dated November 21, 1942, but was from a bundle of design papers, rather than being included in a particular report so the aircraft it was intended for is unknown to me. Yes, there was apparently a proposal to include a rear-facing turret on the Ta 254 A-1 and the drawing shows profiles and weights for a DL131/1 (solid line, 340.2kg), DL15/131 (double-dotted line, 302.5kg) and WL131 (single-dotted line, 283kg).
The drawings around the edge of the preface show (clockwise from the Me 609 in the top left corner), Heinkel P 1079 (otherwise unknown version), Focke-Wulf Ta 153 wing detail design, Focke-Wulf tail turret, Fw 191 cabin brochure drawing, Dornier Do 335 wind tunnel model with pointed nose, DFS Robbe test flight photos, BMW 028 turboprop, Blohm & Voss BV 141 B cabin layouts, AVA 'large aeroplane' designs, Arado Ar 240 V1 WNr. 0001 weights, Arado Ar 65 aerodynamics, Focke-Wulf Ta 254 A-1 turrets, Junkers EF 100 breakaway zones, Junkers Ju 85 mock-up, Messerschmitt Enzian E1 scale plan, Messerschmitt Me 210 wind tunnel model and Me 209 wing test model and Messerschmitt Me 328 flight test photos.
