Don't know what the neck is exactly, as I am not stripping it down. Looks like similar grain through the color, so I am speculating maple or mahogany.
I will take some pics as it is almost finished getting its rehab and just got its first basic setup with the new bridge, tailpiece and nut.
Interesting note, I think I have at least made a good educated guess at the date of the guitar. Looks like 1978.
The wiring inside the control cavity seems to be original, and the grey insulation on the wires to/from the 3 way toggle say "Pacific 1978" on them.
I don't know who "Pacific" is, except I speculate they are a Pacific based wire/cable company.
But its clearly a 1978 date on the wire. Maybe check your cavity wiring to see i there is a date on it?
It may be luck of the draw as it might be covered up in the passthru areas and not visible.
I tried to get a clear picture of the words on the wire, but its simply to small for my camera to get clearly.
