This lot consists of a pair of vintage western silver conchos manufactured by Keyston Bros. of San Francisco, California. The conchos feature domed centers with floral-style decoration surrounded by twisted rope borders and finely engraved floral and foliate scrollwork. The reverse sides are marked "KEYSTON BROS. / S.F. CALIF.", identifying the well-known leather goods supplier founded in 1868.

The conchos remain in Very Good condition with an attractive aged patina and light handling wear. The rear mounting bars remain intact and functional. These classic western conchos display beautifully and would make excellent additions to saddle, tack, belt, holster, or leather restoration projects with authentic mid-century western character.
