Gary Martin, of Martin Model & Patterns in Portland, Oregon, has
made a set of patterns for the two Wurlitzer cast-iron castings:
the "A" frame, and the pulley / flywheel.

Gary is an expert pattern maker and the castings are beautifully
done in cast-iron.  These casting are exact copies of the original
Wurlitzer parts.  For more information or photos, Gary can be
