It's a pretty standard layout, probably a cmos keyer that someone
wired on an experimenters board using telephone wire. You can search
through the arrl handbooks for information on earlier cmos keyers.

I've seen a few like it, HRO ("hugh rip off")(not really) which is is Ham
Radio Outlet put out a pre-built one knob keyer back in the 80's that
looks just like this circuit, less the mechanical keys. There were also
projects like it in the handbook, based on revisions of the earlier wb4???
designs... which migrated into the Autek Accu Keyer layout.

It took me almost ten years to find one, but I did locate a replacement
which included the circuit diagram. I could make it available on the
http://sonic.ucdavis.edu server if you're interested.

The small board underneath is probably a 555 timer set up for sidetone. My
old World Radio Labs Galaxy III (3) didn't have one, so we'd have to
monitor our outbound cw by listening to the power supply hum.

cheers
