    Based on the gear case it is a pre-1949 to 1950 model, when the gear case was changed. The gear case is the basic ‘storm boat’ model with side fins that have been cut off either by the factory or a dealer. So it looks like a 1946 to 48 model.
    The air horn looks like someone adabated a Vactuir carb to it an just drilled a hole through the front cover to make it fit. They would have to remove the compression release linkage to make this work. This is why there are plugs in the cylinders.
