CDM3 CD Clamp Upgrade Kit

This is the clamp arm assembly used to replace the original CD clamp arm assembly (see last photo) used on early Wurlitzer CDM-3 players (machines made prior to serial number 30090000) - this had a white puck that held the CD in place by spring pressure. The downside of this was it put too much load on the CD spin motor and any undue friction would cause it to stop playing reliably.
