Foro de Filatelia Argentina

Does anyone know the meaning of the 3-I-3 format for this postmark?

These cancels were used in 1935/36. This format was mostly replaced during 1937, even though a small number of small towns kept the format well into the 1940s.



I have seen these for I-1 to I-5. I wonder if there's a 6, 7,...





Anyone have more of these to share?

This is an interesting error: the stamp was issued January 1, 1936 and couldn't have been cancelled in 1935.

Does anyone know which city and for which reason was this postmark used?
