This is a larger boiler for the Bachmann 2-6-6-2, designed for the San Juan Pacific cab-forward kit. It comes with boiler, the front boiler mount, back head, a choice of smokebox fronts and drill jig for the optional deck and cab-forward pilot truck.

The boiler has internal passages for 3/32 and 1/16 tungsten rods for weight and strength, so "Liquid Gravity" weight can be used.
