"plus what is Wulf then , considering it is also in the Focke Wulf ?"
I think, it's just an attempt by a non-german speaker to give a "german" name to
what is said to be german project ... and an evidence, that this name wasn't invented
in germany !
If you have a look at all those german projects, you'll find names all over like "Würger" or
"Rammer". And names with "Wolf" are obviously especially liked by those people, probably
because translating is easier for them ...
To my opinion, most of those names are simply fakes, at least with regards to aircraft, there
were very few "official" names.
And "Wulf" in the companies name has nothing to do with the big bad wolf, it's just a name ..
