From Wikipedia;
A typical European casting alloy contains 94% tin, 1% copper, and 5% antimony.
A European pewter sheet would contain 92% tin, 2% copper, and 6% antimony.
Asian pewter contains a higher percentage of tin, usually 97.5% tin, 1% copper, and 1.5% antimony. This makes the alloy slightly softer.
... "fine metal", was used for tableware (http://en.wikipedia.org/wiki/Tableware). It consisted of tin with as much copper as it could absorb, which is about 1%. ... "trifling metal" or "trifle", was used for holloware (http://en.wikipedia.org/wiki/Holloware). It is made up of fine metal with approximately 4% lead. The last type of pewter, known as "lay" or "ley" metal, was used for items that were not in contact with food or drink. It consisted of tin with 15% lead. These three alloys were used, with little variation, until the 20th century.
Now get this;
Britannia metal or britannium is a pewter (http://en.wikipedia.org/wiki/Pewter)-type alloy (http://en.wikipedia.org/wiki/Alloy) favoured for its silvery appearance and smooth surface. The composition is approximately and typically 92% tin (http://en.wikipedia.org/wiki/Tin), 6% antimony (http://en.wikipedia.org/wiki/Antimony), and 2% copper (http://en.wikipedia.org/wiki/Copper).
Britannia metal was widely used as the base metal for silver plated household goods and cutlery.[5] (http://en.wikipedia.org/wiki/Britannia_metal#cite_note-5) The abbreviation EPBM on such items denotes "electroplated Britannia metal".
English Pewter (http://en.wikipedia.org/wiki/English_Pewter) (approximately 91% tin, 7.5% antimony and 1.5% copper)
So, EPBM would be a rich source of tin, copper and antimony from op shops and second hand dealers or pawn shops or perhaps even scrap metal dealers.
