No idea what that thing is... looks sorta like an old 190 Benz, but the hood shape and size is wrong.
Whatever it is, it has had a lot of sheetmetal scabbed onto it... MT, were you surfing CL, or did you see it in person? If in person, were those rivets or sheetmetal screws?
Looks like it might have had the beginnings of a boat-like teak deck over that rear section at one time...
