Not being an expert at sheep-identification, I'd guess that this could be a Blinkhaar Ronderib Afrikaner sheep. Feel free to comment if you disagree. :)
I read something interesting about the origin of sheep in Southern Africa. Apparently there's no evidence to suggest that there were any sheep in Southern Africa 2000 years ago! It's believed that the Khoi-Khoi people (who migrated from central Africa) introduced us to the wonders of lamb and mutton! Now don't we all just love the Khoi-Khoi? Of course we do! :D
