This is a very early china platter from the Delaware & Hudson Railroad. The pattern, named Saratoga, was used in the very earliest 20th century approximately 1905 - 1915, when the D&H was transitioning its main interest from canals into railroad operations.
Condition is lovely and a pretty display, with NO cracks, chips, flakes or repairs. "the D&H" script logo is clear and bright with good color and no glaze blurs. The pin stripes are distinct. If you tilt it in bright light you will see some surface utensil marks but nothing worse. There may be a few very light age spots but hardly any.
This is VITRIFIED china, which the railroad went to England to buy because of its quality and the fine reputation of its maker, Ridgways. We checked in our "Restaurant Ware Vol. 2" book (Conroy) which confirmed the bottom marking time period, circa 1912 - 1915. Included in the bottom mark is L. BARTH & SON, NEW YORK , a distributor/supplier company that would have done the ordering for D&H officials. The word VITRIFIED is stamped into the bottom, along with numbers 40 but we do not know the meaning of the stamped numbers and Conroy is silent on early date codes.
SIZE is approximately 7-1/2 inches wide by 11 inches long, a nice workable medium size, perfect to set off smaller items placed in front of it in the china cabinet.
