of or the purity of or the number of parts of platinum, iridium,
palladium, ruthenium, rhodium or osmium in any article.
(2) APPLICATION OF QUALITY MARK. (a) When an article is
composed of mechanism, works or movements and of a case or
cover containing the mechanism, works or movements, a quality
mark applied to the article shall be deemed not to be, nor to be intended to be, applied to the mechanism, works, or movements.
(b) The quality mark applied to the article shall be deemed
not to apply to springs, winding bars, sleeves, crown cores, mechanical joint pins, screws, rivets, dust-bands, detachable movement rims, hatpin stems, bracelet and necklace snap tongues. In
addition, in the event that an article is marked under sub. (1) (e),
the quality mark applied to the article shall be deemed not to apply to pin tongues, joints, catches, lapel button backs and the
posts to which they are attached, scarf pin stems, hat pin sockets,
shirtstud backs, vest button backs and ear screw backs, provided
such parts are made of the same quality of gold as is used in the

(3) TRADEMARK. If there is any quality mark printed,
stamped or branded on the article itself, there must also be
printed, stamped or branded on the said article itself the following
mark, to wit: A trademark duly applied for or registered under
the laws of the United States of the manufacturer of such article;
except that if such manufacturer has sold or contracted to sell
such article to a jobber, wholesaler or retail dealer regularly engaged in the business of buying and selling similar articles, this
provision shall be deemed to be complied with if there is so
marked on the said article the trademark duly registered under the
laws of the United States of such jobber, wholesaler or retail
dealer respectively; and in such event there may also be marked
on the said article itself numerals intended to identify the articles,
design or pattern provided, however, that such numerals do not
appear or purport to be a part of the quality mark and provided
that they are not calculated to mislead or deceive anyone into believing that they are part of the quality mark.

applied to any article shall be equal in size and equally visible,
legible, clear and distinct and no quality mark which is false, deceptive or misleading shall be applied to any article or to any descriptive device therefor. No more than one quality mark shall be
applied to any article and such quality mark shall be applied to
such article in only one place thereon except as elsewhere in this
section specifically permitted.
(b) Wherever in this article provision is made for marking the
number of parts or percentage of metals such number or percentage shall refer to weight and not to volume, thickness or any other
basis.
