Here are three different ferry boats. They all have the same dimensions of 12″ x 4.5″. The boat to the left is a model #965, the one in the center is a #355 and the one to the right is a #354. There is very little difference between the three. The #965, appearing in the 1952 catalog, does not have an angle cut to the deck where the metal ramp attaches. The #355, appearing in the 1954 catalog, has the angle cut to the deck at the ramp attachment point. The only other difference between the two is the #965 came with two cars and two trailer trucks and the #355 came with two cars and one trailer truck. The boat to the right is a #354 that appears in the 1956 and 1957 catalogs. There is little change other than using decals for the windows. The vehicles are still the same with two cars and one trailer truck. This particular one is from 1956 because of the Harbor Belle decal on the hull, which did not appear in 1957.
