I have a set of the Canadian "Karsh" QE II stamps overprinted with a "G". They are not a variety of any kind, just the normal overprints so, I am not putting in an image, but are the stamps of Unitrade / Scott #O 33-7.
What I am wondering is why does the Unitrade Catalogue list only the U/L corner plate blocks. My overprinted "G" stamps are all the L/L corners only.
Does the Unitrade Catalogue only recognize the U/L only, or do the newer editions list all corners. My catalogue is 2017 and does not give a CV for the L/L corners.
