So there's 5 different dies used for the U-1 through 10; I've found the below cut square that if it's used, the cancel is not noticeable. Anyway, it's on buff paper, curved edges (at the three) but I have no idea which die it is. I did some research and believe it may be a U6 but would like to know if anyone can give a better idea?
Thanks again,
Dave
