The barrels on 88787 were referred to as Fine Damascus a description for ordinary lay man in catalogs and were not usually placed on lower graded guns. The same holds true for Chain Damascus on lower grade F hammer guns. In my records I have only 4 listed out of hundreds and am fortunate to own one. Whether a mix up at the factory or ordered that way who knows. When in the "white" they all look alike and possible put in the the wrong bin.
