No. 3 will be preserved, but there are a few things that need changed back to original.  The paint and lettering is one of them.  It does not have the original paint on it.  Originally the tractor was painted with lamp black and varnish.  We will be using paint, but it will have a dull finish like the original.  The integrity of the tractor will be maintained.  That is the most important thing according to the Smithsonian.
