Rein escribió:The 23p Quebracho has been mentioned in the catalogues with 3 types of paper:
- mate nacional
- mate importado - blando and duro
- tizado importado
Let's see what we can display:
Parallel watermark, vertical direction of paper, asymetrical paper wire, probably described as imported paper:
all the other types have an orthogonal watermark!
to be continued .....
So far we know - and that took some time - that we have FOUR types of paper:
A - Zárate paper, uncoated, orthogonal watermark, Asymmetrical paper wire structure, direction of paper horizontal! The back of the stamp (but also at times the front) shows long lines parallel tot he direction of paper! Mate Nacional
B - Wiggins Teape paper, uncoated, parallel watermark, Asymmetrical paper wire structure, direction of paper vertical! Mate Importado Duro
C - Zárate paper, coated, orthogonal watermark, asymmetrical paper wire structure, direction of paper horizontal! Tizado Nacional
D - Kupferschmidt paper, uncoated, orthogonal watermark, symmetrical paper wire structure, direction of paper verticall! Mate Importado Blando
A-paper was issued on 15.06.1965.
