On vintag SG's (60-69 ish specifically), is the back of hte neck ALWAYS cherry? For example, I have a 68 Jr that I picked up in bad condition, it has since been refinished in Pelham Blue. Yummy! Anyway, the body was painted black and the back of the neck was cherry or bare mahogany. Is this normal, or would that imply that the color was originally the cherry option?
