Oils and or other items for long storage of firearms?

Yes. Grease or cosmoline. Oil will eventually work its way toward gravity. Don't wrap the greased part in foil either.

Inside the wax was a perfectly pristine 1860 Colt revolver.

Now I"m curious. How did you get all the wax OFF of the revolver...

Cosmoline is grease. It's literally thick petroleum jelly just like Vaseline.
Silica packets require replenishing periodically.
Do it on the cheap is done with regular vehicle grease, lightly applied, and storage someplace dry with constant humidity. Isn't really a big time science project.
