I have a friend that wants to get his grandfather's Edison Diamond
phonograph operating again.  He brought over what he thought was
the reproducer.  Unfortunately, all he has is the connector part of
an aftermarket lateral cut reproducer.  He has a good collection of
Diamond Disks and the phonograph is in a high-end case with two-level
record storage.  It has the "Official Laboratory Model" tag.

He would like a Edison Diamond Disk Reproducer and possibly a lateral
cut reproducer as well.  Does anyone have one for sale or could you
point me in the right direction?
