Hi there Revi16,
Yes, it's clearly a "langnase Dora".
I checked out your film with Thomas Genth's excellent website dedicated among others to the flying career of his father Karl-Georg Genth; his last flight aboard Fw 190 D-9 W.Nr. 500 118 took place on 7 March 1945, as his was shot down by F/O. Basilios M.Vassiliades's Tempest Mark V EJ 755 coded "JF-E". He could fortunaetely bail out and save his life albeit wounded.

Mr. Genth does publish three stills taken by the gun camera of F/O Vassiliades and I tend to think that youy Youtube movie plays it out
in extenso.
Great find anyway. This reminds me of the thread asking about photos of Fw 190 D-9's in flight some weeks ago here. Another piece for the D-9 file!
Cheers
Marc
