The "Any Interest in World Postal Stationery?" Thread/'Topic has been locked, so here is an attempt to continue the topic with new postings.
The New Zealand KEVII postal card of December 13, 1907 shown here was used on March 3, 1913 from the Commanding Captain of the Marton Senior Cadets to Pte. H. Nafel (senior cadets) in neighboring Bulls, NZ. Manuscript "not known in Bulls" is written above the addressee, and the card was returned to Marton by the Wanganui p.o. Return date is April 14, 1913.
Card tells cadets that there will be parades at Bulls (pop. 1500) Town Hall on March 5th and March 19th. "Absentees are liable to a fine".
My net search showed no military school or academy in little Marton (pop 5000), but subsequently, I was educated at the NZ government history site.
From nzhistory.govt.nz, "The Defense Amendment Act 1900 introduced military cadet training into schools. The Defense Act 1909 made military training for nearly all boys compulsory from the age of 12." Photograph of 1913 shows military cadets at Lyttleton docks marching past HMS New Zealand
