Built with a 12 1/2 Set

The O pawls for the rippers and the MF for the fenders are slightly modified

S57 1 3/8 screws are used under the frame to jack the model up so it can operate stationary.

2,Z,flanged wheels are used for the upper track wheels.

It looks like Maurice has had a lot of fun with his bulldozer. Notice the wear marks on the P13B gear.
