Here’s an interesting item from the Aug 7 1917 issue of The Australian Philatelist.
There is an item (supplied by a G. Turnbull) that the legal name of Port Moresby was still Granville. He writes:
“There were two townships, Granville East and Granville West. The term ‘Port Moresby’ only applies to the harbour.”
I have no idea when Port Moresby became the official, legal, entity.
And later in the article:
”Mr. Turnbull has a friend in the island who has something unique in the way of Papuan stamps. It is SG No 83 with the word ‘Papua’ spelt ‘PCAPUA’. Has any other collector of these stamps seen this variety?”.
I don’t know if there was any reply to the query – anyone come across that?
