I think the venue is a sort of pre-war, show-and-tell event. There are placards in front of some motos.
Rikuos? Type 97?
My dad had a Rikuo when he was stationed in Japan. He likened it to a '36 Indian. 1000 cc's (he'd call it a "61"). He wasn't all that impressed with it and eventually swapped it for a vvvv 73 (cu.in.) Harley. vvvv

The model 149 Blenheim Mk IV was a cross between the earlier 142 and the Bolingbroke. Bolingbrokes were only made in Canada. Mk IVs were made in the UK as were the Mk V, Model 160, with a different nose again. This three view is of the Mk IF which has the gun pod under the belly as well as the Mk IV and V..

Just found this on Wiki's Blenheim page...

"Consequently, Fairchild Aircraft Ltd. (Canada) of Quebec started production of the Blenheim Mk IV as the Bolingbroke (the originally intended name for the Blenheim IV)."

Apologies for the mis-ID on my part. Seems the Mk.IV and the Bolingbroke were the same plane, though. Just built in different places. Makes Sense.

The same plane with a LOT of differences. For example the Bolingbroke had wing and tail de-icing boots - the Blenheim did not.

The Bolingbroke could be (and was) fitted with skis and floats. The Blenheim could not and was not.

I learned the hard way - trying to work on Bolingbrokes using a easy to get Blenheim manual when Bolingbroke manuals were thought to be extinct.

That is a very nice installation and obviously depends on aerodynamics to keep the ski at the correct angle of attack which means a LOT of time was spent on those aerodynamics.

Compare that with the Canadian version with a complex mickey motion hydraulic trim system to achieve the same results or even the DC-3/C47 with its wing that was a pure bitch to set up and the cables to limit the angles that the ski could move when the gear was extended. And if you think that is a lot of stray cables then you are correct but all are needed.

The upside is that the Dakota skis could be retracted in flight to reduce drag and also had a raise/lower mechanism so that you could operate off both snow and gravel/tarmac/concrete on the same flight. When you land on snow you MUST lift the ski off the snow when you park (to the position shown on the near side in the photo) or the hot ski can melt the ice - and that is when your problems really start if the ice freezes again. Note the far side ski has drooped and would probably stick on ice/snow. Often the oil cooler is moved up the side of the cowling on the inboard side and and I never saw one with that box thing attached. Each Dak ski weighed over 200kg from memory and installing them was not fun. Removal was easy though.

All I know is that when a ski equipped C-47 appears in a movie very bad things happen

Great movie but also worth watching the first 10 minutes for the flying scenes alone.
