The wood shows 100% the original finish. I added no wax, tung oil, or anything similar.

I was able to deep clean the surface using original GoJo hand cleaner. (the smooth kind, no pumice or abrasive)

I rubbed it by hand with 00000 steel wool (5 zeros) and the GoJo hand cleaner. This technique also works great for cleaning old painted surfaces. I used it on the cast engine base as well.

Of note, if you clean a surface with GoJo, it may soften the original paint and you want to avoid touching it for a day or 2. 
The paint will harden up again.
