The Caterpillar D5K2 LGP Dozer in 1:50th scale was in 2015 re-released by Diecast Master under #85281.
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 D5K2 LGP Dozer, already released by Norscot in 2013 under number #55281. In addition to the luxury tin packaging from the Diecast Masters "High Line Series" with information about the 1:1 machine, the Caterpillar D5K2 LGP Dozer was also modified on a number of points and re released under #85272. Of course Bob the operator came to sit in the cab!
