CZ FR5 1926 Canal Zone

Operator: Henry Cronkhite
On this QSL card the prefix "cz" was added as a country identification code for the Panama Canal Zone. In 1927/1928 the call-sign was changed to nzFR5 (according to the international intermediate prefix nz for the Canal Zone), and in 1929 to KFR5 (also written as K-FR5).
