I am putting labels on some Ampico roll boxes and want to use the
appropriate A or B labels.  Is there an easy, quick way to tell if the
roll inside is an Ampico A or Ampico B roll?

If I remember correctly, the B mechanism has an extra hole at either
end of the tracker bar which would put a perforation nearer the left or
right edge of the roll.  Do these perforations always occur near the
beginning of the roll?  If you measure these extra B perforations, how
close to the edge of the roll do they come?

Any help or suggestions are appreciated.
