The Caterpillar 309 CR "Next Gen" Excavator in 1:50th scale was released by Diecast Masters in 2019 with #85592
The new Caterpillar 309 CR Mini Excavator, also announced as the "Next Generation Design" or short “Next Gen” Caterpillar Track-Type Hydraulic Excavator is the successor to the "D" Series in 1:1th scale, but because Caterpillar has changed his machine type numbering and stopped adding the successor letter it just will be released as the "309" Series.
If you are in the possession of the original hardcopy spec sheets, brochures or photos about the 1:1 Caterpillar 309 CR “Next Gen” Mini Excavator I would be happy if you send your response to info@minimovers.nl
