1:50 Thumb for Cat 330D/330D

This 1:50 Four tine thumb is designed specifically to fit the Norscot and Diecast Masters Cat 330D and 336D models. I also offer thumbs to fit various other excavator models, and will be releasing more over time. 
The thumb is designed to use 1/16 brass rod for pins. The thumb mounts to the lower portion of the coupler.  This model comes with a spare set of cylinders just incase. Some assembly is required upon delivery of the printed item and the hydraulic pistons will need to be separated from each other.
** Caution this item has very small parts that could pose a choking threat to young children**
