1930s - An Early Boat, Trailer and Caille Motor

I haven't a clue where this image came from 13 years ago (says the file date).

The AOMCI  Caille Special Interest Group Leader says it is a"1931-34 Caille model 15 or 16. Can’t tell is it’s a straight blade prop or a variable pitch."
Another member of AOMCI commented, "Trailer wheels, spring & axle are early 1910 +\-. "
