Trans Canada Airlines Lancaster

Larry Milberry, Aviation in Canada, McGraw-Hill Ryerson 1979
During WW2, several Lancaster bombers were converted to passenger/mail planes to fly the transAtlantic route. Though intended mostly as fast mail carriers, 8 to 10 uncomfortable passengers could be accomodated. During the war about 500 flights were completed having delivered 1,500,000 lbs of mail.

1972 Bolens 440 Sprint

The 2017 Owls Head auction featured what looked like someone's snowmobile collection being sold off, there were a number of rare machines, this is a 1972 Bolens Sprint- 440 cc I believe- judging by the flip-up headlight. This was the last year of the make. 
 Bolens started out in the snowmobile market in 1965 selling the Montreal-made Hus-ski tractor-type snowmobile with sleigh. In 1967 the company redesigned them and now made in the US, sold them as Diablos before introducing the convention Sprint line in 1972.

Dead grass color, mmmm. Nice. By the vintage catalogs listed for sale online, the H H Kiffe company seems to have been a sporting good retailer around the turn of the last century.

Tucker

I've been re-watching some old movies, and found this 1988 Francis Ford Coppola movie starring Jeff Bridges (along with his father and a list of other stars).  

A good flick, but I'm sure not without it's historical inaccuracies or misrepresentations.

Preston Tucker was an American dreamer and businessman, also involved in the development of a "Tiger" tank, a 100 mph+ armoured scout cars.  There are lots of youtube videos on it.

There are reportedly still 47 of the original cars still in existence, including one discovered in an Ohio barn.  For a good, short Smithsonian video, look at A Rare Look at Tucker Cars.

Now I've got to try to find the 2008 film, "Flash of Genius", in which Robert Kearns takes on the Detroit automakers who he claims stole his idea for the intermittent windshield wiper.

Messerschmitt M20

Armand van Ishoven, Meserschmitt, Gentry Books 1975

The M20 was a single engine passenger or cargo plane designed and built in 1928. Though the prototype crashed on its maiden flight, the plane entered service the next year. They were used by Luft Hansa till 1937. Due to Messerschmitt's almost fanatical attention to reducing weight and improving aerodynamics, the M20 could carry 90% of its empty weight in cargo. 15 were built, none remain.
