DW 5000 dual chain single bass drum pedal for parts or repair, not working.

This pedal is missing a bearing, maybe some bushings, the spring assembly and cam, and beater.  It is missing the set screw on the beater holder.  It may be missing other parts.  The pedal hinge is tight and in good condition, the pedalboard is strong, the frame floor plate, sprocket and chain are all solid, but show plenty of signs of use.  the axel is a bit rusty, it also may not be original, but I can't be sure.  Lots of good parts that are pretty expensive on the new market.  Feel free to request pictures of specific features.
