There are very few photos of this autogyro inspired by the Kellet KD-1A and built by Kayaba.
This one is the Kayaba Ka-go 2 with a Jakobs L-4 M A-7 air-cooled, seven-cylinder engine.
The story goes like this: the IJAAF imported a Kellet KD-1A from the States for evaluation. Unfortunately it was damaged during trials and the Army gave it to Kayaba to repair it. Kayaba installed a Jacobs engine and produced one more experimental test machine designated Ka-2. It was found to be very satisfactory and the Army decided to put it into mass production as the Ka-1 but with a different engine; an Argus As 10c eight-cylinder.
It served as artillery spotter and, according to a Japanese reference, with the 107Sentai.
It also served in the anti-submarine role equipped with depth charges from the Army aircraft carrier (yes, the Army had some of those too) Akitsu Maru. The first in the world to do so.
A rare photo I'm sure X-plane lovers will like.
Those who have the Francillon volume will notice some differences with the text above.
By the way...it's overall orange.
