The Caterpillar 336E Excavator in 1:50th scale was re-released by Diecast Masters in 2016 with #85279.

When Diecast Masters acquired the Caterpillar scale model license rights from Norscot and Tonkin Replicas in 2015, a number of models from both manufacturers were included in Diecast Masters' new "High Line Series" program.

This also happened with the Caterpillar 336E Excavator, already released by Norscot in 2014 under number #55279. In addition to the luxury tin packaging from the Diecast Masters "High Line Series" with information about the 1:1 machine, the Caterpillar 336E Excavator was also modified on a number of tiny points, for example a black painted excavator bucket and re released under #85279. Of course Bob the operator came to sit in the cab!
