NOTES:

1. This pattern, when realized, usually varies from the patented design -- for example, the silver threads are parallel, not divergent, and a band of short flutes is sometimes added. Spillman (1996, p. 290) incorrectly calls the pattern "Silver Diamonds and Silver Threads". Elsewhere, the Sinclaire photo-inventory refers to these diamonds as "strawberry diamonds", the name that is given (correctly) to the cross-cut diamond motif when it is used, in whole or in part, as the name of a pattern. Silver diamonds, on the other had, refers to the strawberry (or fine) diamond motif when this cutting is used, again in whole or in part, as a pattern name, principally by C. Dorflinger & Sons. It is a propriatory name and, therefore, should not be used as a synonym for strawberry (fine) diamonds. In any case the "silver-diamond" motif does not appear in this patented design.

2. Sinclaire (1974, p. 38) indicates that Adam No. 2 was patented. However, a search of the patent indicies for 1915 and 1916, kindly undertaken for the writer by the Reference Department of the Erie County Library System, has failed to find any patents for these years other than those listed in this table. Sinclaire made a mistake.

Bowl Cut in the Patented Snow Flakes & Holly Pattern by H. P. Sinclaire & Company

A hexagonal bowl cut and engraved in the Snow Flakes & Holly pattern. Patent no. 41,204 for this design by H. P. Sinclaire was granted to him on 28 Feb 1911. This bowl was abused, resulting in excessive surface wear that has removed the acid-etched Sinclaire trademark. This abuse also resulted in a quarter-size chip which is visible in the four o'clock position in the photograph. Restoration is possible because the chipped area, which includes only engraving, can be smoothed and re-engraved. This item is considered a rarity. Max D = 8.5" (21.6 cm), H = 3" (7.6 cm), wt = 2.25 lb (1.0 kg). Sold for $425 in 1989.
