Actually if you look at it its a rear engine machine. The guy is sitting in it. A really early can am spyder! I wonder if the door was old military surplus??
Okay, I'm doing some digging now. Here's another picture, while I figure out the rest. "Mr. Graham's novel three-wheel car designed to look like an armoured car, being used to take himself and his bride on honeymoon after their wedding. (Photo by Fox Photos/Getty Images). August 1931"
I found this caption for this picture:
"A three-wheeled car made by Mr. A. Graham of Kingston, Surrey. The vehicle, designed in a nautical style, reaches a maximum speed of 70 miles an hour with a body made entirely of sheet iron. (Photo by Fox Photos/Getty Images). April 1929"
