Updated update!

The admins finally let me on the Jackson/Charvel forums and here's what I found about the Model 7:

Year: 1988
Origin: Japan

Electronics
Pickup(s)
Bridge: J120 Jackson USA Telly Single Coil
Neck: J100S Jackson USA Single Coil

Controls: 1-Volume, 1-Tone, 3-way blade pickup switch

Body
Wood: Ash
Style: Offset single cutaway (similar to Fender Telecaster dimensions)

Neck
Wood: Maple with a reversed headstock
Fretboard: Maple
Inlays: Black dots

Hardware
Bridge: Black Gotoh Telly Bridge
Nut: Black Plastic
Tuners: Jackson Die Cast (6 in-line)

The key here is that I now know that the body is good wood so this project wouldn't be a waste of time from moment one.
