The catalogues state that these are the Italian stamps of 1863-72, "with corner designs slightly altered" (Scott  ) or "modified corners" (Gibbons ). Gibbons lists nine issues in its first set, illustrated above, while Scott includes two 1878/79 issues to make eleven. Most of the values have suffixed design variants (e.g. Sc1c, SG1b, "two square dots in lower right corner") that are outside the scope of this exercise.
Scott describes the stamps as used in "Italian Post Offices which, for various reasons, were maintained from time to time in foreign countries" Gibbons is rather more specific, listing them under Italian Post offices in the Turkish Empire and provides considerable detail on their use.

For both the Italian stamps, the initial sets (September 1917) were hand-stamped locally and later sets (December 1917) overprinted mechanically in Italy. The first sets are expensive (the Peking stamps range from $200 to $260,000).
