Sterling silver tribal style salt and peppers

Have had these for several years, finally unpacked them last month, they are really interesting and i may have overpaid, but then again, i have never seen another pair, in the 50 years i have collecting. Hallmarked 925( sterling silver ) stand approx 16 cm in height , in the form of a totem/drum with either monkeys or natives climbing up the sides as salt and pepper pots , they still work with my African theme, but if anyone knows more about these, it would be greatly appreciated
