WW2 Era Photo Etc of Sergeant Richard Pring South African Airforce

A bit of a conundrum with this collection, the back of the photo is named to Richard Percival Pring and it is accompanied with a brief printed family history, a National Rifle Association certificate and a hallmarked silver shooting prize spoon. The family history info has Richard serving with the South Africa airforce and the photo bears this out based on his cap badge and the location which is probably SA, he was British born and earned his shooting certificate and prize spoon in 1929 at the Mustapha shooting range in Alexandria Egypt, so somewhere between living in Sussex in 1901 to being in Egypt in 1929 to being in South Africa during WW2 Richard moved around a lot, I have not been able to trace any service papers for him so there's a challenge for you! All items come in good condition.
