The top stamp is flat plate printing and should gauge around 11.90 and the bottom stamp is a rotary press printing and should gauge around 11.25 x 10.50, but most catalogues round off to the nearest 0.5 perforations so that the top stamp would be 12 and the bottom stamp 11 x 10.5 perforations per 2 centimeters.
