The Morgan wood is ash, not something used when crafting a fine shotgun, I feel. Wood for a gun stock is often walnut, or something similar.

The Morgan ash frame has already been soaked in cuprinol and white spirit.
I suspect that light machine oil will keep the wood waterproof and discourage corrosion in the adjacent metal. Even so, I use ACF 50 when I "oil the beading".
