Don't cry for Argentina - 01 c

A second group of Argentina 'labrador' stamps, are  those with the honeycomb watermark.

There are two version, each with two sub versions.
The main difference between those stamps, is whether the honeycomb is placed vertically, or horizontally.

vertically placed honeycombs or horizontally placed honeycombs

Type 3 or 5

When we see the honeycomb (or hexagonal) placed vertically, we need to check if it's type 3 or 5.
Type 3 (and later also type 4) are German printings, type 5 (and later also type 6) are Italian printings.

The difference between type 3 (or 4) and 5 (or 6) lays in the thickness of the hexagonals.
In most cases the German types are easily to recognise, as the watermark is clearly visible.
The hexagonals appear as broad, fat, rounded, where the Italian hexagonals (type 4 and 6) are more refinded, thin, angular.

If the watermark isn't clearly 'narrow and fine' we're dealing with a German printing (type 3 or 4)
If the watermark is more difficult to see without a watermark detector, clearly angular and fine, it's the Italian printing (type 5 or 6)

Type 3 (vertical - broad)

 

Type 5 (vertical - small)

Type 4 or 6

Same remarks as above, but now the hexagonals are placed horizontally.
The Italian printings are more fine as can be seen in the picture.
