UNITED STATES: 1929 to California with combination franking of KGV 1d & 2d tied by superb Melbourne cds & US Airmail 'Wings' 8c cancelled in transit at Sydney, a couple of minor opening tears. A rare cover. [Flown San Francisco to Los Angeles]
From 1923, the internal US airmail rate was 8c per zone for each of three zones. Mid-1927, this was changed to a flat airmail rate of 10c = 5d. In July 1928, the fee was reduced to 5c. On 6.7.1932, the fee was raised to 8c = 4d, which remained until 30.6.1934. However, from 1933 the Australian 'Post Office Guide' no longer mentioned the possibility of prepaying the US airmail rate with American stamps. This is probably why the 8c was not cancelled in Melbourne but it begs the question 'Why was the article not taxed?'
