Based on the construction shown (locally-made leatherwork, scalloped/hand-finished edges, simple stud-fastened square pouches sized for 5-round Mauser stripper clips, and a plain brass buckle), this is best identified as a South African/Boer-era Mauser bandolier intended for 7x57mm Mauser ammunition in 12 x 5-round clip pouches (60 rounds total). The layout and “economy” leatherworking style is consistent with regional saddle-maker production seen in southern Africa around the Boer War and immediate post-war period, rather than later mass-produced British issue patterns. Condition appears fair to good for age with noted losses (approx. 2 missing studs) and general scuffing, but leather remains serviceable/soft.
