Hi all,trying to identify the stamps on cover, this is what I think:
1. Type 2, scott 11A
2. type 2, but only right innerline recut, scott 10A
3. Type 1, scott 10
4. Type 1, scott 11 (below the upper left triangle is the design made of an extreme small lined triangle, other than normal I think)
interested to learn my mistakes if I made any
thank you all in advance
