Hi! The Gasuden(瓦斯電)model-2 drawing.
The Gasuden model-1 was a biplane. The Gasuden model-3 was a monoplane, not realized.
Through model-1 to model-3, engine, fuselage, undercarriage and tail stabilizers were common.
And the pictures of ITo 28-31 flying boat.

Those Japanese designers were definitely influenced by recent developments in Germany and USA.
For example: Gasuden Model 1 biplane's forward-swept landing gear was influenced by Bucker Jungmann, but it has a lower-drag NACA engine cowling.
