Model Railroader Quarry Hill Project Crusher and loader Question?

Does anyone know what kit or kits were used to make the quarry crusher and loader on the Model Railroader Quarry Hill Project layout? I saw the video on the construction of the asphalt shingle plant but never did see a video on the quarry rock loading plant? Thanks

This was described in the March, 2013, issue. Parts from Walther’s kits 933-3062, Glacier Gravel Plant, and 933-3017, New River Mine. Additional parts from Plastruct.
