Plate sequence proposal for the 50c and 2 pesos values

Based on the plate varieties I have come across that are unique to a specific range of papers for these two values, this is the sequence of plates I think were used:

1. The first plate was used between 1936 and 1948 on the papers 1E1/2/3/4, CL1B(2p only), NGR and NOP.
2. The second plate was used between 1949 and 1952 on the papers 2C, 1L1, 1L2 and CL2B.
3. The third plate, on the 1L5, or Zarate paper for the 50c and 2 pesos, and the 1L3 paper for the 50c, was used in the mid 1950s.
