Can anyone help me with what this is as i havent got a clue?
All I can think of is one of the Culver types. From memory I think Ed Mooney had a big hand in the Culver company; before he established his own outfit. Remember the WWII Culver drone aircraft used for gunnery practice.
Note the Oshkosh truck plant in the background
It's a Culver LCA Cadet built in 1940.
