   Andy -

   The original black japanning is asphalt based.  When applied and then baked, it will form an almost glass hard surface.   The original formula is sometimes referred to as "Pontypool Asphaltum".  I make my own using the original highly guarded secret recipe.  :)

   (knowing the ingredients ain't the hard part!)

   To remove the rust, use electrolysis.  Nothing else will neutralize the rust that has formed INSIDE the porous cast iron.  Afterwards scrub with hot soapy water and a scotch brite pad.  Bake to remove the water absorbed by the cast iron.  Brush on about 3 coats of Japanning, letting it dry betewen coats.  Then bake at no more than 400 degrees for 2 hours in an electric oven.  A gas oven can be used if you first pre-heat the empty oven, then turn off the heat while the plane heats up.  Turn the gas back on after the plane has gotten hot.  (moisture in the gas combustion)

   Do the above, or, send it to me!  :)

   .......or you could just clean them up with a wire brush and spray them with black Tremclad!!  If it is not the original finish does it really matter?  If you are doing this to resell, then that is one thing but if you have these planes just to use yourself, you have to wonder if it is worth the effort.  ....just a thought.
