I believe that this is a home built cabin and front ski Assembly,modeled after the Bombardier snow mobile ,but in this case a Canadian Armoured snowmobile was used complete and the cabin and front ski assembly was added to the machine enclosing the driver..
An early Penguin...
More research would be needed and wiser than I would have to research it,but those are armoured snowmobile tracks and road wheels..many of them were sent to Norway and Russia,late war ..they had V-8Cadillac flat head engines in them so if any of those parts are still kicking around ,they could have been from that machine..
Nice Find,...
This picture is probably post war and the Armoured snowmobiles would have been war surplus..maybe early '50's...may even been Norwegian Army vehicle as I see uniforms and hat badges on some of the men gathered around your father..
