1950s Kenworth "Bullnose". Chassis kitbashed from the SuperBoss race truck and a KW Aerodyne cabover.
The SuperBoss has a KW torsion bar suspension for a single rear axled truck. Those of you who remember the original KW mixer kit know that there was a tandem rear axle torsion bar setup there.
Am waiting for Dave Natale to cat up new 6-hole/10-bolt 1950s wheels for this project.
