Perforations

It appears that 3 different machines were used to perforate this set measuring Perf 10, 11.75 and 12.5 and these were used either vertically or horizontally. Examples can be seen throughout the set of compound and mixed perfs using these values. Although not all possible combinations of these perforations have yet been identified, it is likely that further research on this set will prove fruitful.
