Roman,
     In the days when top tubes were all about 1 inch in diameter, it was easy to convert between center-to-center and center-to-top specifications. So it was not an issue, as long as you knew what method was used by a particular builder. Once you're in a situation in which different top tube diameters might be used for various bicycles, the c-to-c dimension really looses its meaning.
    So my impression is that c-to-c was more common in the past - but in any event, local custom dictated which method to use.
      Best regards,
