Brass - Wood - Metal
The Stiff Leg Derrick, like the prototype, can be custom built to fit varying space situations. The kit can also be used to build a Guy Wire Derrick, as used in quarries, and with the addition of the HOClam Shell Bucket (P141-HO) sold separately, (Price $12) can be set up for loading or digging. The kit also features a Bull Wheel to rotate (or slew) the boom from side to side. The Bolt-on Hardware with Bolt Head Detail are photo etched brass.
