Here's several models from Jim Groeneweg's collection. The Mack MR concrete pumper was built using a resin cab mounted on a Kibri Mercedes concrete pumper. The two mixers delivering fresh concrete are a twin steer Mack RD600 and Western Star. The Mack RD uses a resin hood from Ralph Ratcliffe mounted on an Athearn R cab. The Western Star is a Jacobs Models resin offering. Both mixers have Herpa mixer barrels mounted on scratchbuilt chassis.
