Hello Ed,

To be more precise: the He219 production in Vienna/Schwechat had its own subcontractors with their own ID-codes. There are more distinctions between A-0, A-2, A-7 and D-1 subtypes, which can be seen in the so called 'Bauausführungs Übersicht He219' of the Ersatzteilliste. This shows lots of similar (standarized) parts with the same construction group number for all He219 subtypesing (the de-icing equipment for instance had main constrution number 950, regardless the He219 subtypes).

However, as advised in a very early stage when the He219 was still on the seabed, the salvage/restauration team should look for construction numbers which are distinctive for each subtype. In this case the wing would be the best chance, because the wing for He219A-0 had main construction number 501, the wing of a He219A-2 had 506 and the He219A-7 had 512. But now we know of the found DB603 E-1 engine, we already know that it was an A-7. It is a fair assumption, that the wing - if it has 512 somewhere painted/stencilled - will finally confirm this.

Now your questions:
#1: I have no knowledge whether the NASM actually had 506 somewhere but if it has, that would support my strong believe that the NASM is actually Wnr.290202 and not 290060 as rumoured elsewhere.
#2: There is some data for the Czech produced fuselages (in Mielec) but I have no info yet about the number of produced wings so far
#3: No, they are not the same and so far I haven't found any indications for an airfield full of new He219's. OKL Reserve could perhaps mean, that aircraft stayed with units without official acceptance by these units, this is still an issue to be researched.
#4: several contacts with historians of R(C)AF Squadron Associations have resulted in new, never published He219 photo's

Turning all stones over is exactly the purpose of the He219 Project I am working on (:-).

All the best, Marcel
