I have never seen the like of these before, at least nowhere near this tiny size. Must be for a toddler or pre-school child and I almost wonder if there was not an expensive vintage western Cowboy doll these went to although I doubt it. Very Good quality leather with nice finish and top workmanship on the tooling and they are Very Good or better quality which is way above what you generally find. But I don't expect they were "played with" much.
IDEAL for a collection or I might suggest one of those studios that takes "vintage" pictures of people dressed up in old timey styles. Hard to find either one at all and much harder to find a set that was kept together. Fits onto a standard belt.
Color in the photos is just a shade rich but not far off, and conditioning them would make them look like that or better. The metal pieces are nice and shiny with no corrosion.
