Very little is known about the Sinclair pattern flatware (unnumbered), aside from the fact that it originially comprised approximately 374 pieces and was service for sixteen (see Larry Pristo, Martelé 950-1000 Sterling Gorham's Art Nouveau Silver, 2002 p. 395).  This is by far the largest Martelé flatware service produced, and represents an incredible survival.
