Johnson Cowkeeper Brass Miniature Show Churns

Very very rare miniature all brass show cans(churns) made for E (Edward?) Johnson Cowkeeper. Second can reads Special Cows for Infants and Invalids. Height 7.5 inches. Made exactly the same as the rare full size examples in brass. Hinges are both broken, one tap missing and one front hinge missing ring. Despite the minor damage it does not detract from there rarity. In 50 years of selling high end dairy antiques these are the first pair I have seen in this diminutive size. C 1880/90.
