Sa Wings sealed patterns

[Badger44]

I have a friend in South Africa who is seeking information on SA wings, I give below his words out of an email he sent me, as follows:
'I am trying to find the Sealed patterns or art work of the 1st series of South African Para wings. These were from 1960/61. When we became a Republic we cut the Apron strings with Britain, but we never had our own Heraldry department until 1963, so all this was done in England. In SA there is no record of any artwork, art cards or approval. This should all be in England somewhere. I presume that this is kept at the same place that the British sealed pattern badges are kept. I would love to get photo’s of these or even the actual sealed patterns for my research.'
Can anyone help him on this? I have no idea where to suggest he look but knowing how knowledgeable members of the forum are, I am hopeful someone may suggest some avenues we can try.
