Thanks for the tip Jim - I investigated the 244 earlier, nothing fitted. But it looks like a Gnome-Rhone engine, so I got sidetracked looking at rare French transports.
German?
Was the Gotha-Kalkert Ka 430 ever fitted with engines? I keep looking at the nose-wheel - wouldn't be too many WW2 era gliders that used them?
This aircraft is definitely the Ki=105 "Otori" tanker-glider-thingy. I was looking at it over and over again and I just now noticed the cockpit windows and nosewheel were extremely similar.
Bingo! And I don't even have to post the plane! All yours amigo... Was kind of looking forward to Graeme posting some obscure french transport though...
