Rein,

The work you are doing on the 1pNGR-SO complements well the work Luis did from a complete sheet the 1 peso no boundaries 'Servicio Oficial' he examined in this thread:

Este trabajo sobre el 1pNGR-SO es un buen complemento a la labor de Luis basada en una hoja completa que el estudio en este hilo:

Rein,

Back to the classification of plate varieties:

I have not come across any plate varieties that are found in every single stamp of the sheet. Such a variety could only be distinguished if there was more than one plate and the difference was found from one plate to another. To me this type of plate variety is really a plate type. For instance, the 10c Rivadavia Red Type I and Type II differ only by a few very tiny dots all next to each other.

The other two types you mention make sense to me, and I especially like the use of the term 'plate flaw.'

-----------------

Voviendo a la clasificacion de las variedades de plancha:

No he encontrado caso en el cual una variedad se repita en toda la hoja, y si esto ocurre, y solo para unas planchas y no para otras, lo que tenemos es un tipo, como es el caso del 10c Rivadavia Rojo, en el cual la diferencia en el tipo I y el tipo II son unos minusculos puntos.

A la manera en que describe los otros dos tipos le veo sentido, especialmente al uso del termino 'defecto de plancha.'

Tony,

you are right saying it is not worthwhile calling it a 1st type characteristic as long as all stamps [of all plates we know] have the same - like that dot of the 1 peso, the dot of the U of Urquiza, the tiny scratch of the 30c and probably a few more....

Still I suggest to trace those tiny bits and register them as might indicate new plates!

Should certain plate miss those dots or scratches then we have to speak of another type like the 2 types of the 10c B. Rivadavia, the 3 types of the 20c G. Brown [there are 3 types not 2!].

An indication of a new plate is certainly to be established when we find a new set of the 2nd type characteristics as I did with the unwatemarked 1 peso. I don not think we had these set of characteristics before - unless Luis has found them already. I will read his worknow.

Tony, Luis

I had a look at the sheet - that is the parts where the S.O. is - and could not find the characteristics I had shown before so as I expected it is a different plate.

I could however recognize a few characteristics in that sheet thast did repeat in every [!] odd horizontal row AND horizontally in the 5th column fartheron....

So indeed, as you mentioned somewhere earlier, the base block consists of 10 stamps = 5 next to each other and 2 above each other. The complete sheet of 10x10 was subsequently reproduced as 2 block next to each other and 5 block on top of each other..

In the case of the 30c Lanas - at least the one with the Ministerials - the procedure must have been slightly different.

The 10c Rivadavia:

The stamps without the characteristics:






The stamps with the characteristics:

[Rein]

The combination of the tiny dot underneasth the first "A" of "Argentina" and the horizontal "-" left of the 10c tablet occurs way too often. In 64 copies of the type II 10c red without "overprint" I have 21 copies with these characteristics; in my 25 copies of ministerials and S.O. I have 7!!

A subtype of this is the dot on top of the first "V" of "Rivadavia":

and taht subtype has several subsubtypes !

As I had announced before the characteristics are also present in (the first printings?) of the 1c Rivadavia type II in chestnut with the dot on top of the first "V" of "Rivadavia":

[Rein]

Some do not have the dot:







None of the chestnut stamps I have seen so far has the dot underneath the first "A" of "Argentina"....

[Rein]

To some this looks like fly-speck philately, which it is!

The tiny little dots and scratches can tell us much more about the way our stamps have been manufactured than the large, spectacular plate flaws that hardly anybody can overlook!

Searching systematically for repetitive patterns is something that everybody can do! But it has to be learned and practised....

----------------------------

Para algunos esto parece buscar minusculos detalles, lo cual lo es!

Estos pequeños puntos y arañazos nos pueden informar mucho sobre como fueron impresos nuestros mas que lo pueden las variedades de plancha espectaculares que pueden ser distinguidas a simple vista!

Buscando sistematicamente por patrones repetitivos el algo que todos pueden hace! Pero primero debe ser aprendido y practicado....
