I have a photo of a Flettner helicopter doing trials on a platform on top
of the ‘X’ (or BRUNO, auf Deutsch) turret on one of the “K-Kreuzern”
(is that the right plural?) – KARLSRUHE, KOLN or KONIGSBERG – but the ship
is not identified in the Schiffer book on German helicopters, and the
trails aren’t mentioned in Whitley’s book on German Cruisers; I have teh
first Marine-Arsenal volume by Breyer on these vessels but it only covers
their careers through ’37. Does anybody know which cruiser hosted these
trials?

(KOLN, at least, should have an umlaut…)

Also, does anyone know which vessels beside the DRACHE ex Yugoslav ZMAJ
carried the service model Flettner helicopter in the Aegean in 43-44?

Thanks,
