Back scans for the six stamps. I may be confusing the 1E3b with the 1L1.
Here is a back scan of what I am calling a 1E3b.
I am saying this stamp is 1E4 for now, but the 1E4 is always horizontal and this one is vertical.
This sample includes nice 30cNGR (common) and 40cNGR (rare, especially used).
It also includes a nice selection of 30c2C's (four vertical and one horizontal) and 40c2Cs (one of each vertical and horizontal).
The small spot in the background of one of the 30c2C's could be a plate variety.
