Way to go "khj"
The Kingdom of Two Sicilies!
The biggest clue was the "2", then "dead" and range of years.
Two Sicilies never issued an national issue. Scott #1-7 were for Naples, 1858; #10-18, were for Sicily, 1859. The Provisional Government issues #8-9, out of order in 1860, were produce by the Garibaldi government in the spring 1860 captured Sicily and most of Naples by September, but Garibaldi needed help from Victor Emmanuel II of Sardinia to finally crush the remaining Two Sicilies government/army at Naples. Garibaldi turned over all control of his captured territory after the victory, in late September, to Victor Emmanuel II. I always found it interesting the fact that Scott never mentions the government of Garibaldi. On Scott #9 is the Cross of Savoy representing Garibaldi's home of Nice, Savoy.
The Neapolitan Provinces issues, Scott #19-27 were actual never officially issued (but listed), even so, by this time, 1861, the provinces were already part of the new Kingdom of Italy, no longer independent.
Great job everyone for playing.
