Similar to our "O"Scale Kit 322,this is a small two cylinder steam engine designed to control the "Bullwheel" of a stiff leg derrick. This engine allows the derrick boom to swing (slew) to the left or right. The slewing engine takes steam from the hoisting engine boiler.

The engine measures 1 1/2" Wide - 1" Back to Front and 1/2" in Height.

Used with our Stiff Leg Derrick Kit 214 & our 3 Drum Hoisting Engine Kit 218

The slewing engine can also be used as a side-by-side two drum winch.

Cast Pewter construction
