Hydrocopter, anyone?

In the very lame and not very thrilling 1979 thriller Bear Island, less than loosely based on McLean's novel of the same name, cool airboats/snowplanes are featured. Sleek-looking with an open canopy, engine in a pod behind the driver, one propellor, two rudders behind the prop and a retracting "claw brake" aft.

The closest I have found is an Arkösund hydrocopter:

Does anybody here have any information on those vehicles?

You'tr talking an air-boat/swamp-buggy, right?

Here's the Swedish version.

My thread starter clearly indicates I am looking for information on what appears to be an Arkösund Hydrocopter, such as specs, manufacturer's history, other products they made, etc. All I can find online says the Hydrocopters were made beginning in the sixties into the eighties with small changes. I am not at all interested in info on Gator Clyde's swamp boat and other craft. Are there any Swedes here?
