Originally prepared for the W kit, this casting contains detailed scale draughtboxes, couplers and a hook.

Coupler holes are pre-formed, and one coupler has the draught pin cast in place.  The castings can be made to self center by gluing 2x 1.0mm  x 0.5mm magnets into the cast in recesses .  magnetic centering provides good performance without risk of excessive force derailing wagons.

Coupler retention is intended to be via a 1mm screw.
