All significant parts are etched or cast brass. The model features our usual suspension system for smooth riding and excellent track-holding.  This kit features many features to ease construction.  All key parts fold or slot in place to minimise positioning problems.  The hopper is a single etched part that folds up. 

Couplers and sidechains/hooks not included, but available separately.

The hopper is fully detailed inside and out, and is removable.  Hinges and latches look far more complicated than they are.  Innovative fold and laminate techniques make these parts a doddle.
