Eightbore hit that nail square on the head. Still, it is an admirable work in many, if not most, regards.

On the white line thing, one has to wonder if it was not in part based on the spats from an earlier era, a sign of class as in dressed to the 'nines', smart & stylish. White wall tires were a way of calling added attention to the common rides during the depression era and afterwards though they too were from an earlier time and sent a connotative message of 'expensive'; actually quite inexpensive in the scheme of things & dressy. Its called 'Retro' styling today, on M/C's anyway. Weatherby also was into the white line motif and undoubtedly some influence transferred or kept the interest there anyway through the 50's & beyond. Gunsmiths got a little extra for installing a white line spacer pad on guns, whether considered blasphemous, classy or be-bopper cool. I wish they still made the 'Pigeon' pads.
