Hi, Many years ago when I was selling copiers and fax machines I had a customer in Sheffield called "The Standard Piston Ring Company". I've just had a quick look and it appears they are still going (in Rotherham now).
Without looking too closely, their main web page talks about making rings between 11 mm and 17 metres so maybe they can help?
Best wishes in your search,
Nick
