Status of this study

Just to give some context for my process, the 2008 postings in this blog constitute a single pass at the complete series with many holes. The outcome was the 10 booklets in Word format. I am currently working on a second pass in which I fill the 2008 holes and in the background am updating the 2007 PDF book to include all of the officials. At this point I have completed the 1E1 and 1E2 issues regular and official and am at 100 pages! Just this week I am working on 1E3/4/5, CL1A/B and 2D, basically every paper used before 1945, when the NGR unwatermarked paper was first used. Here is a quick chronology of the papers:

1. 1E1, October 1, 1935 and throughout 1936.
2. 1E2, 1937, mostly on the large format values.
3. 1E3, 1939, when several color and engraving changes were instituted for the small format values.
4. 1939, CL1A, on the 5c Moreno and 10c Rivadavia Brown.
5. 1E4, 1940, a small run on all values, yet, incredibly, a relatively large printing of the 20 pesos stamp!
6. Additional 1E3s, and 1E5 during the WW II period, 1941 to 1944. This time period is chaotic for the papers and deserves a lot of additional study. Because of time constraints, I may fill this hole after this current, second pass.
7. 1943, CL1B, on the 5c, 10c, and some of the large format values, including the great rarity of the series, the 2 pesos clay with dark colors.
8. 1943 2D, the diffused straight rays paper.
9. 1945, NGR, the unwatermarked grid paper.
10. 1948, NOP, the opaque unwatermarked paper, printed on most values, with the three high values well represented.
11. 1949, 2C, the clear straight rays paper.
12. 1950, CL2A, used for the 10c Rivadavia Brown.
13. 1951, 1L1, different paper, but same watermark as the 1E3.
14. 1952, 1L2, rough paper with large to gigantic RA.
15. 1952, CL2B, the last clay paper, on the 10c and several large format values.
16. Onwards with the remaining 1Ls, which I have not yet studied well. My current numbering is not chronological. The 1L3 in my current scheme is actually from 1955. There are five papers in my current scheme, but I suspect there are a few more. There may be a third clay paper in the second batch uniquely used on the 25c 'Servicio Oficial' stamp.
