Below is my copy of 41L7 that I mentioned earlier in a discussion of the imprint.
Plates 5 through 10 used the same imprint transfer roll as was used for Plate 4, but to indicate the new owner, "Casilear" was omitted from the plates by first rocking in the names "Toppan, Carpenter" and then turning the roller to add "& Co." Various degrees of irregularities occurred in the process which can be helpful in identifying the plate. On 41L7, parts of the "Ca" of "Casilear" can be detected in the background of "& C" of "& Co."
