AB. Chronologically the Focke Wulf design predates the B29 design but only just. I think that the similarities are coincidental however- Heinkel Dornier, Bell and no doubt others I can't think of right now had all designed or flown aircraft with a fully glazed contoured nose in or before either of the types you talk about had flown.
F2 my thoughts were exactly the same, but confusingly all the placarding and instrumentation appears Anglicised (at least the bits I can make out) As a result I shall run away bravely so someone else can ident it. Still strip gauges, electro mech instruments and what looks like an early IN by the co puts me in mind of late 70s kit.
Not an An72 Coaler or variant thereof?
