Within our group of Caterpillar collectors are builders who built various custom versions by using standard scale models as a donor for their custom project.
Friend and fellow collector and custom scale model builder Gertjan Veld used the Caterpillar D9R Track-Type Tractor from NZG and a white metal boom kit made by HIMOBO in 1:50th scale to create his custom built Caterpillar 578 Pipelayer.
Enjoy the first photos! Curious for more? I have added add the complete review from the Caterpillar 578 Pipelayer with more pictures from the scale model, machine in 1:1 and background information in the category Pipelayers.
