[Boatanchors] Hallicrafters SX-42 - Restore or Parts?

[David Stinson]

I just picked-up a (heavy!) Hallicrafters SX-42 receiver
here in the Dallas area, brought to HamCom by a friend from Denver.
It was obviously left where a fine mist of water could hit
the front pant, which has lots of shallow rust spots through the paint
and will need a complete work-over.  Case and trim ring
also need a complete re-finish.  It has the original round S-meter,
which I'm told is tough to find.   The switches and some of the 
controls
are seized, but can probably be freed.  The band switch rotates
and looks OK.  Knobs look OK.
Chassis looks pretty fair with the only significant rust spots
on the right vertical support member and on the transformer shield.
I've certainly seen worse sets recovered.
The very complexity of this set will make it a big project.
I'm not a Hallicrafters person.  I don't know if an SX-42 is 
considered
worth recovery or if I should "part it out" to help other sets.
Advice, please?
