In 2005 Ken Kemp visited and interviewed James Roller who operates the only website and restoration studio in the world dedicated exclusively to diggers. This 30 min. DVD was produced as an historical record.
A number of different makes and models were on hand and the filmmaker produced a fine record of them for the collector/investor who is interested in antique cranes and how they were operated years ago.
Jim comments on many of the machines.
Some of the makes and models that are shown are:
– The Panama Digger
– 1934 Electric Traveling Crane
– Exhibit Supply
