Time to get to know a few aspects of Chile stamp printing!
At first some strange perforations that resemble what we saw in the Argentina 1c Girasol!

Comb with 32/26 teeth hor./vert. used for quite some commemoratives of Chile, but we also have plenty of stamps that are a bit narrower but with the same length! We are seeing the stamps here placed so the comb strikes from top to bottom....
We need a base line of pins plus 25 pins across to completely perforate a row of stamps...

This could be the same comb 32/26 but with 3 pins taken out to result in 32/23! But still the stroke was a bit short giving a sharp tooth at the bottom...
to be continued ...
