Vintage Horse Head Brooch Silver Tone Equestrian Pin Bridle Chunky

Vintage Silver Tone Horse Head Brooch Great statement piece for an equestrian! It is unmarked. The metal feels thick and chunky like pewter and is shiny, maybe electroplated? I have seen similar versions that were marked Fine Pewter and Sterling. This one has no markings or signatures. Good used vintage condition with some wear due to use and age. The bottom edge is a bit rough. It is unmarked. I do not know what the metal is. It could be pewter or silver or something else.
