1937 horn mounted on "left side of cylinder head" (maybe someone will post information about this?)

1949 standard/single horn mounted on intake manifold - old style horn

1950 standard/single horn mounted on intake manifold - old style horn

1953 standard/single horn mounted on intake manifold - sea shell style horn

The 1954/55 seashell style horn/horns were mounted on the front of the radiator housing. The intake manifold in 1954 might have had holes for the horn on the intake manifold "buss/boss/bump" or might have had no holes in that mounting "buss/boss/bump", depending on how late it was in 1954.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
