SACS Butt Disc Marking

Any one know the meaning of this Butt Disc marking, I have looked in both of the books covering these markings and can not see it.

Any South African markings on the rifle, such as a broad arrow or a diamond inside a U?
Could be Home - South African College High School

St Albans Cathederal School?

Thanks chaps

No evidence of SA Service

I found S.A.C. which is South African Constabulary.

Or South African Constabulary Sisters my main man........ I always thought that the SA Police were controversially called the BRITISH South African Police - or the BSAP

Peter, BSAP were Rhodesian - the enforcers for Cecil Rhodes' "British South Africa Company".
There never was a "British South Africa"; initially South Africa was the 4 provinces (Natal, Cape, Orange Free State, Transvaal) and then confederated 1910-1961 into the Union of South Africa, and since 1961 the Republic of SA.

Brian, South African Constabulary would be a distinct possibility... if only one could explain the second S.

Not on a rifle unfortunately but here is a similar one from my collection.
The 6 prefix may help or confuse identification?Attachment 64666
