Kenworth C500 Concrete Mixer & Mack MR600 Concrete Pumper - By John Ross
John Ross built this Kenworth C500 concrete mixer using a Dennis Aust resin cab kit mounted on a Promotex chassis with a mixer barrel mechanism from Herpa. The Mack MR concrete pumper was built from a Kibri kit with a Ralph Ratcliffe Models resin Mack MR cab replacing the original Mercedes Benz cab.
