Rather a neat vintage look there.
The wiring stuff can be a pain in the neck because its intrinsically rather random in layout, but fussy with it. If its not an area you're especially comfortable with, post *lots* of photos from different angles and folks here will see what they can do. Different angles is useful because something is always hiding something else.
If you can locate a mate who is into vintage electrics, 50s radios and the like that would be great too. Guitar electrics are kinda 1950s!
