For Seeburg questions or parts, I would recommend either Dave Ramey or
Jerry Biasella.  They are both in the Chicago area, and have extensive
Seeburg experience.

Dave Ramey (whose phone I do not have at the moment) has created many
Seeburg reproduction parts as well as complete machines, and Jerry
Biasella (tel. 708-756-3307) is a literal walking encyclopedia of coin piano
information.
