The very earliest "Made by Westclox" dials have the name "BABY BEN" the same width as "Westclox" below the center. Most have "BABY BEN" wider than "Westclox". This applies to the plain (non-luminous) dials; MAY apply to the Ivory Brown Band Luminous dial; and PROBABLY doesn't apply to the Black Luminous dial, which started out with different widths as a "Made by Western Clock Co. . . ." dial and continued with different widths as a "Made by Westclox . . ." dial.
