The one at the Muster sold.
http://onlinemilitaria.net/products/4281-UK-1903-Pattern-Leather-Cavalry-9-Pocket-Bandolier/It came from WPG, and quality was superb. It did need to be softened with Lexol and pouches stretched to accommodate paired 5-round clips in each pouch, though. It was used for 5-round clips of Swedish Mauser 6.5. Meant for .303, it wouldn't have fit that caliber without major stretching. Originals were of slightly thinner weight, I'm guessing. The original ordnance patterns were developed in 1897, or so, and would be appropriate for Boer War, although named as 1903 Pattern.
I will offer that the 5-pouch Infantry bandolier that WPG also sells would've been more practicable in retrospect. Hard to bring those four pouches on the back of the cavalry bandolier into play when in use during a stage.
