The Caterpillar 980K MH Wheel Loader in 1:50th scale was released by Diecast Masters in 2018 with #85289c in their "Core Classic Series".
When end 2015 Diecast Masters took over the Caterpillar Licensee from Norscot, who produced the Caterpillar 980K MH Wheel Loader in 2013 under #55289, it was in 2016 directly released within the new Diecast "High Line Series". Besides the "MH" (Material Handling) Configuration both Norscot and later Diecast Masters simultaneously released a "RH" (Rock Handling) Configuration. The difference between both "MH" and the "RH" version is the specific wheel loader bucket and tires.
The Caterpillar 980K MH Wheel Loader is re-released by Diecast Masters in 2018 within their "Core Classic Series"
Apart from Bob the driver and the Diecast Masters "Core Classic" cardboard packaging, nothing else has been added or changed to the original Norscot scale model.
