Nakajima Ko 4

[Jorm]

Does any one have any reference or information on these planes , i have now found two sources that state the japanese licence built 600 of them (Nieuport_delage NiD.29.C2 )

But thats about all i can find on the japanese use of the aircraft. I know they were used by the Japanese Army aviation.

i'd like to add them into WPO but am after as much info on them as i can get before i do so.

thanks
Paul
