Hi
that is the
Voortrekker Monument, in Pretoria, South Africa, and was inaugurated on
16 December 1949 to commemorate the Great Trek and the Voortrekkers
The trekkers were those who, in wagons pretty much like those used to move west in the USA, moved north from Cape Town and colonised South Africa
Here is a link to the history
http://www.sahistory.org.za/pages/specialprojects/great-trek/great-trek1.htmVERVAARDIG is Afrikaans for "manufactured" and so your piece says "manufactured in England"
It may have been produced in 1949 at the opening of the Monument
Previously part of the British Commonwealth, South Africa became a
Republic in 1961, so it is unlikely to have been made after that in England.
