Vintage Brass Horse Stirrup

The item in the image is a brass horse stirrup, likely an English or Fillis style. This type of stirrup is traditionally used in English riding disciplines, though the heavy brass suggests it may be a vintage or antique piece, possibly for a side-saddle or an ornamental item (e.g., a door knocker or wall hook).
