Twin cylinder Harley Hummer

From the same source as the Plymouth Monster article, 'Motorcycles in Competition' by Hank Wieand Bowman (1952), this magnificently eccentric home-brewed Harley Hummer tandem twin.

Through the magic of the web I found the history of the bike here:
http://www.motohistory.net/news2005/news-sept05.html (scroll down to see the article on the Hummer).

Wonderfully the Hummer still exists, still works and is in the Wheels Through Time museum in the States.
