TOPIC:

Local Unit would generally mean one raised in South Africa on a semi informal basis. i.e. SAC is the South African Constabulary and there are many others. I sort of agree with Mike on the Black Feathers. ( I once owned a slouch hat with those feathers. ) The boots are actually lace up shoes and the general issue style for the British Army. Also I note the inside knee reinforcement which would generally provide additional "grip" for a mounted trooper.

The "strange leather strap" commented upon is the steadying strap for the Mounted Infantry bandolier. These days, that strap is very seldom seen. I must say I like the pic; a pity he obscured his medal clasps! Years ago, I fired quite a few rounds through a Webley .455" Mk.4 revolver in an informal practice. Quite heavy, but easy to control. The big lead bullets sure packed a punch out to twenty or so paces.
Unfortunately, I cannot assist with the uniform, apart from what has already been said.

Hi
Hi
These are some SAC items for sale on auction.
Look at the black feathers for an example.

I think the South African Constabulary is likely correct.

Hi there, I am writing a book on Boer War veterans - can I have permission to use this excellent photograph as an illustration? kind regards

Just realised this is an old thread over 3 years old. However ,its raining and I'm in lockdown 2 so had trawl of the uniforms.
The uniform is certainly mounted infantry. The hat is being worn at a very jaunty angle which gives us not many clues except for the feathers.
On closer inspection there seems to be some feathers poking out under the brim. I have had a good look at uniforms this morning and nothing has been a close match. I do like a challenge and will keep browsing. There was a New Zealand mounted infantryman with a similar tunic with no front pockets but different headgear. As for QSA & KSA they relate to his covered medals. Queens South Africa & Kings South Africa . Will keep looking but there were many local South African regiments but we should be able to eliminate a few regarding the feather plumes on his hat.
