As real as other German projects !
That site is very similar to Luft'46 and sources probably were very similar, too, probably, lots of books like
Griehl, Rohde or Novarra and the like, as is indicated by the drawings and pictures. So, what's shown generally
is accepted, I think, as "real projects", although bibliographies are in most cases hard to find in such publications !
Reproduced drawings often look like original documents, maybe even rubber stamped in the corner. So, are those
authentic documents ? Who knows ?
And if one type is mentioned in two, five or even more books or websites, is this really an evidence for authenticity ?
Or just, that all those used the same source, maybe a false one ? Sorry for that, but due to the nature of your question
hesham said:
and as Toura send a drawing and info,they are a real projects or not ?.
I thought it worth to point out once again, that the existence of drawings and data and even a obviously plausible
develomnet aund service history is NO guarantee for reality ! Very often, with regards to projects, we just can try to
check sources and so form an opinion .
