[F1(2) Article 5 shall apply as if a new sub-paragraph were added after paragraph 2(e) substituting in section 4(3)(b)(ii) of the Act “550” for “650”.]

(3) Where a silver article is struck with the mark indicating a standard of fineness of 830 the article shall be struck with the relevant assay office mark set out below instead of the mark set out in column (2) or (3), as the case may be, of paragraph 1 of Part 1 of Schedule 2 to the Act.
