19 19" Hawker biplane wheels
19" Hawker biplane wheels, This earlier design is made up from an aluminium alloy extruded rim, coiled and welded together. This is riveted to two spun alloy discs, which are then riveted to a cast hub, which takes the brake drum. This design is even more complex than the 15" wheel, and entailed investing in many 100's of feet of extrusion and other major tooling. Again supplied either in unpainted metal, or for a little extra painted in the traditional Dunlop bright silver paint.
