I have placed these stamps in group 5, and find some overprints on any or both of 1E1 and 1E2.



Here are all the images

Those overprinted along the top are all 1E1 in my limited sample, and this may be an indication that these were overprinted first.



I also find a specimen with a field of ink dots, similar to one I have shown before.
