Gumbreaking patterns are well-known aren't they?

[Rein]

The gum breaking pattern of German and Austria stamps are well-known?! But is this true??






Looks familiar!

The 1948 Folklore dresses of Austria:





Quite like the Germans stamps!

But in Austria in the 1955-1957 period also another type of gum breaking had been used that wasn't mentioned in the Michel Special Catalogue nor in the Austrian Netto Katalog!







You can even see it at the front!!!

Nothing special it seems!

But this is something the German collectors do not know! Argentina collectors know better!

Rein,
This topic is most interesting! Do the German written catalogs ignore the existence of these different types of gum breakers or just mention when they show gofrado gum? Saludos,

José,

the German speaking catalogues do mention the wave like gum breaking patterns but ignore the one with the sharp indents! The last examples of the German stamps were primarily meant to fool the German experts in thinking it had something to do with gum breaking..

You and I know this in the context of "granulado" and know it is very common in the PyR II series! On the other hand I started to doubt whether these indents if coming from the wire could have been so sharp!?

What do you think???

Rein,
For me the indents are provoked by protuberances of the warf of wire cloth. I say this 'cause when a production run is started generally they clean the mesh and wires are prominent. As long as the wire cloth is running the gap betwenn wire start collecting microfibers thus making them fullfilled with same. This "flattens" the mesh surface and indents are less deep, thus making paper show less rugosity. That´s my opinion. Saludos,
José

José,

sounds plausible and does also explain the relative scarceness of the stamps with sharp indent.

Another lesser known fact is about the stamp paper produced by Harrison and Sons, UK.

Parallel to the direction of paper, very thin lines seem to have been "carved" in to the surface!

It is quite remarkable in Belgian definitives that had many paper providers.






as before but now the carvings indicated!

Rein,
If you look !c Sarnmiento and 5c Moreno on tizado paper by looking at them flat t the hight of your eyes, you´ll see "valleys" paralell to long side of the stamp-

PS. On Dutch paper from Loeber.

The "askew" gum breaking pattern has also been used for the Austrian Commemoratives!

For the first time for the 1955 Opera stamps:





At the left the orthogonal wavy lines pattern:



At the right the "askew" pattern:

And then the 1955 United Nations stamps:







all with the "askew" pattern:

1956 Wolfgang Amadeus Mozart:







all with the "askew" pattern.
