Spanish or South American Stirrups

Silver plated stirrups of Spanish or South American "bell" pattern. These appear to have been cast in two halves in brass. Each side has a floral pattern. Probably made for use in shows or parades. I am not sure of the age of these stirrups but believe them to be 20th Century.
