25c value colors between 1939 and 1946

This stamp has a complex mix of combinations of color and watermarks. I find the following:

Rose on 1E1 paper



Rose on 1E2 paper



Rose on 1E3 paper, used in 1941/42





Neat, bright colors, from 1939, on 1E3 paper.



Neat, bright colors, slight plate wear, from 1945/46, on 1E3 paper.





I also find this latter stamp on the 1E4 paper.
