The broad top teeth points to the perforation running vertically from bottom to top!

The bridge in the horizontal perforation shows it is running vertically!

There are quite some stamps with the perforation going from bottom to top!

First some examples of the Stinnes paper [since 1390] with an orthogonal watermark and the wire side printed [!!!]; the felt side has a flat surface whilst the wire side shows grooves [surcos]. This means that the dandy-roll had RA! Dandy-roll RA -> felt side AЯ -> wire side RA....

The 10c is the only value also having this watermark with the direction of paper horizontal!!

Rein,
Avery fine observation concerning perf comb running from bottom to top. However the 10 x10 counter sheet have (describer yesterday) show that in THOSE shhets perf goes from top to bottom.
On the other hand, according to Tenorio Casal, the stamp with the direction of paper horizozntal would be the 10c verde oliva. Merry Xmas!!!

José,

Merry Christmas!

First some examples of the Berger [?} paper [since 1932] with an orthogonal watermark and the felt side printed; the wire side has a very rough surface showing grooves [surcos]. This means that the dandy-roll had AЯ! Dandy-roll AЯ -> felt side RA -> wire side AЯ....

The extension hole at the right is good enough to show the perforation goes vertically!

Not all JSM stamp have the vertically running perforation! As we could see in Rodolfo's sheets of the 12c the perforation goes from left to right! It may turn out that this was the predominant situation in the period 1923-1930!

It is difficult to find good examples of the right bottom/top teeth being broader or thinner! What may be an indication of this type of perforation is that the stamps often badly centred! The vertical perforation holes touching the design!

The stamps are on Wiggins Teape paper [from England] with a parallel watermark, the direction of paper is vertical! This WT paper had a rather closed granulado [not so clearly visible rhombs] during 1926-1927, but from 1928 onwards the granulado [the rhombs] are very clearly visible and the indents oft he rhombs as well!
