Heinkel 111J with 4-blade propellers

[Stig Jarlevik]

Hi All

Back in 1974 (in Air Pictorial) Ferenc Kovac sent an ID request regarding a Heinkel 111J that carried two four-blade propellers.

The photo is not very good and just shows the front of the aircraft. The details known by Mr Kovacs in 1974 is listed within the attachment
Attachment 12140

Back in 2002 the same photo was used by George Punka in He 111 in action Sq Signal no 184, but with far less details.

Some further details have appeared, such as there was an International aviation meeting (Intern. Fliegertreffen) in Hungary (Budapest) from 7. — 14.8.1938. The 3. Reich was there with 13 aircraft (5 from the Luftwaffe, 2 from the NSFK., 1 from the German Aero-Club, while all the others were privately owned) [Source "Flugsport" at http://www.luftfahrt-bibliothek.de]
No evidence this He 111J had anything to do with this meeting though...

Since it is the only He 111 I have seen with four-blade props I wonder if it is possible to identify it by now?
Does the stated registration D-ARKO mean anything to anyone?

Cheers
Stig
