Translations:Dunhill Additional Stamps/11/en

Here we have many variables, we need to observe the whole scenario because it depends on where it is graphed. For example, the "C" can indicate the model, a "Churchwarden" - if it is aligned with the pipe style (but it is not in use anymore nowadays - see more about it here Dunhill Shapes). It also can be the "C" for classification of the series "OD" or the series "D.R". It can be a "complementary", in this case, they were over-stamped "not for sale" in addition to the letter. Because it was a courtesy, they usually were not dated not to delimit the warranty period. There is also the "C" of "compliments", destined to British royalty.
