The Caterpillar D11R Dozer in 1:50th scale was re-released by Diecast Masters in 2016 with #85025
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 "Core Classics" program. This also applied to the Caterpillar D11R Dozer, which was already released by Norscot in 1999 as #55025.
Apart from Bob the driver and the Diecast Masters "Core Classics" cardboard packaging, nothing else has been added or changed to the original Norscot scale model.
