Late chiming in, but better than never, eh? I was, at first, thinking not a Thompson, especially when Andreas chimed in, as he is the go-to-guy for all things Thompson.
But, now that I've had a chance to poke around a little, I'm thinking it might be a Thompson "Outboard Rowboat". See attached.
The steam-bent seat braces may imply a wartime boat in this case?
