Opinion.
Your 4 10 paras stamps are genuine.
Notwithstanding the curious perforation holes.
Caveat: I am having trouble translating Birken
He used "Mount" and "Field" I have yet to work out
I think he means plate and row.
Your stamps and mine show common plate flaw Plate 2? (Mount 2)
There are small white dots, just left of centre, under the crescent.
Note: Your 3rd stamp has a stronger bend in the top script, than the rest.
Not aware how they made up the Surcharge formes, but noted.
Also stamp C, top left corner outer frame, does not meet
personally noted.
I see no other plate flaws in our images.
Plate 1, the 1 piastre error, and it's correction.
