Food d\for thought. At the moment I am only referencing the early stamps of Austria, however I think this may apply to other countries early on in 'postal history'. There was no standard for perforations. The catalogues generally list perforations as whole numbers or fractions (1/2, 1/2 and 3/4),. Regardless of method used to identify perforations, most have likely observed that the stamps do not neatly fit into nice whole numbers or if a fraction, 1/4, 16 or 3/4.
perforation gauges fatigue my eyes rather quickly and i now use software, which measures it to hundreths . The only downside I can see is in some cases if averages the two opposing sides...
If (as an example ) the catalogue lists 10 -1/2 as a perforation, but no 10, nor 11, would you place any stamp which lands between 10 and 11 as a 10-1/2 (and we accept that with stamps that are over 100 years old, if there were any recognized variations from what a specialized catalogue lists... they likely have been found by now)
just wondering how others would handle?
and with that I bid you all a good day!
