Down to the Sea in Ships(?) 1949, Model boat with active oars

original model / miniature

I recently purchased this model boat that was used as a prop in a movie. I don\'t know which movie, so I\'m looking for help figuring that out. It looks like the boats pictured in posters for Down to the Sea in Ships (1949), but I haven\'t found a photo of the actual model (https://www.modelshipsinthecinema.com/2020/09/down-to-sea-in-ships-1949.html). The boat originally had a motor that drove gears that caused the oars to row. I have one oar and an oar handle with a doll\'s forearm attached. I surmise that the large appendage below is a buoyancy chamber to cause the boat to float at the correct depth. The wood is very weathered, and the wire is brittle, so I guess that it is from the 1930\'s to the 1960\'s. Any suggestions as to which movie the boat is from? I found a photo of a similar whaleboat model from Moby Dick. That boat had the same buoyancy chamber below, but the hull was lapstrake, not smooth, and there were ten oars, not four (made in the same model shop, perhaps?). I would really appreciate help in identifying the movie in which the model was used.
