With more than 108 years of history, Harley-Davidson Inc. has some unusual stuff in its archives. But few people likely knew the company once made rocket engines used in aerial drones.
Never-before-seen prototypes of motorcycles that were never manufactured are part of it, including a Project Nova bike from the late 1970s that was built in collaboration with German automaker Porsche AG.
In addition to bikes and motors, the exhibit offers glimpses into what it was like to work at the motorcycle factories decades ago.
One item is a small tin pail, like a milk jug, that workers filled with beer on their lunch hour.

The exhibit runs June 11 thru Aug 21 at the Harley Museum in Milwaukee. One more reason Milwaukee is a GREAT city.
