A Twill-binding with a 30/20 density (30 vertical threads/cm and 20 horizontal threaads/cm):





The Argentina watermark has multiple Suns + A#1071; since 1922 but there are various versions of it depending on the manufacturers.

When the line of RA is parallel to the direction of paper, we have a parallel watermark, when the line of RA is perpendicular to the direction of paper, we have an orthogonal watermark.

This distinction is vital! I will come back to the UK/Commonwealth watermarks where a watermark seems to be unchanged but in fact two different watermarks had been used.

As to the densities - quite common was the 30/20 (or 28/18) lines per cm horizontally/vertically!

But occasionally other densities can be found although not so common.

The most often met other version is the 24/22 density which is called "Tela" in Argentina and originated from the Wiggins Teape paper mill in the UK!

Outside Argentina "Tela" can be found for UK and most British Commonwealth countries in the 1939-1950 period.

Even in Australia and New Zealand. Apart from the Argentina collectors ONLY the NZ collectors have been aware of this type of paper! Although they did not specify it other than calling it "coarse" paper....

In the UK the stamp printer - Harrison and Sons - used 4 types of paper in the 1937-1951 period for stamps in photogravure.

NO UK stamp expert has mentioned this in their publications ever! And this is quite surprising as the differences were known to me - my own observations - since the late 1970-ies.

The first type of paper with a symmetrical paper wire and a 28/18 density!




you can see the "rhombs" even at the front!

The second type of paper with a Asymmetrical paper wire!




The "striped" lines I indicated by "red" is called "rayado" in Argentina

The year "1939" is a nice documentation of the fact that this type of paper wire was introduced around 1938!

The "b" version has the less steep diagonal from top left to bottom right; the "d" version has the less steep diagonal from bottom left to top right!

The d-version:

The fourth type of paper is a symmetrical paper wire again with the 24/20 density - called Tela!




The G40 is the turning point here for the asymmetrical into the Tela!
