After doing a bit more research I stumbled upon a post in the Gentlemens Military Interest club concerning Breaker Morant.

it is rather a long posting but in the notes at the end of the post I found the following.
No MAFEKING RAILWAY VOLUNTEERS........................................................................................................................
NOTE : The writer had in his possession until sold in the early 1980's, a medal pair to Alfred Henry Royal, QSA Medal five clasps DoM, OFS, Tvl, SA01, SA02 named “Mafeking Town Gd” , and British War Medal named “Railway Regt”. Recorded as Engine Driver on the Railway Volunteer's QSA Roll, and also on the Mafeking Town Guard Roll and the QSA recorded as issued off that Roll. Subsequently enlisted Bushveld Carbineers, Cape Town, 6th April, 1901, No. 233, Squadron Quarter Master Sergeant, with former service in Railway Volunteers. He one of those who had fled for his life, and his comprehensive report of atrocities committed by the corps recorded in Captain Beddy's report (see No ). He subsequently served to the war's end as a well respected No.32773 Quarter Master Sergeant, Pietersburg Light Horse. Railway Regiment Great War service in the Union and South West Africa only
So it would seem that My Great Grandfather's (Maternal) medals were sold by the writer of the post in the early 1980"s already.
It would also seem that he was one of the men who "fled for his Life" and reported on the atrocities committed by the Bushveldt Carbineers.
I have in my Posession copies of His marriage certificate giving his address at the time as Mafikeng and occupation as Engine Driver.
