25c and 50c bundles part 1: 1E5

I have just received six bundles of 25c/50c stamps, 300 of each.





I find the following papers. The 25c recevied most use in 1943, and the 50c during the 1950s.



The Wavy Rays paper of the 1940s, the 1E3, is really a family of at least three papers:

1. Medium RA on semi-opaque paper
2. Small RA on semi-opaque paper
3. Small RA on porous paper

For now I call the medium RA the 1E3 and the small RA the 1E5, and leave for a more detailed study to flesh out these papers.
