This is an Antique Large Repousse Solid Silver Alloy Muffineer Sugar Shaker. It is marked simply "Silver" on the base and is likely Sterling or higher quality Silver Alloy. It measures 8 inches tall and weighs 123 grams. A few minor dents and slightly off plumb, a little tarnish. If I had to guess the origin I would say likely Australian due to the marking and form.
