Early 1928 cars and AA trucks had a radiator shell with a wrap thru welting (no rivets). Cars were nickel plated, pickups and AA trucks were black painted. Later 1928 radiator shells had riveted welding and the finish was the same. Both of these shells were round under the crank hole cover. 1929 Radiator shells were nearly identical, only the area under the crank hole cover was bell shaped. Still black on commercial vehicles, and nickel on most passenger cars, chrome on Town Cars and some later 1929 cars. In 1930 the radiator was taller, and the grille shells on passenger cars were stainless steel. Pickups and smaller (not AA) commercial vehicles had a steel grille shell paint black. AA trucks had a steel grille shell painted black that was much thicker due to the thicker AA radiator, and it was flat under the emblem ( not peaked). All of these grilles had a blue Ford emblem (in the USA). In 1931 the stainless passenger car shells had the painted recess in the upper portion of the shells, with a stainless emblem. Small commercial vehicles (not AA) had the same steel shell as in 1930 , but with a stainless emblem. AA trucks had the same thicker flat steel shell with a stainless emblem. Ambulances and hearses and a handful of deluxe AA trucks had the same radiator shell , only stainless steel.
