Hopefully I can get some help here...

I have a Gibson era Tobias Classic (oil finish) that needed some major structural work to the neck (new fingerboard) in order to make it playable again. In "fitting" the new board to the neck, I ended up removing a bit of the amber stain and oil on the neck close to where the fingerboard is. My question is, what is the "proper" oil to restore these areas to "original" condition.

Somebody help me please....

Thanks,
Steve
