Clockwise from left to right: the Dutch lion rampant under a crown, province of Holland 1st standard mark silver 934/1000, maker's mark IH on either side of a tree in a rectangular frame for Johannes Horstman, town mark of Amsterdam, the three Andreas crosses under a crown, year letter A for Amsterdam 1785.
Johannes Horstman was initially listed in the literature as Johannes Hartsman, see the books by K.A. Citroen, Amsterdamse Zilversmeden en hun merken, issued 1975 and Karel A. Citroen, Dutch Goldsmiths' and Silversmiths' Marks and Names prior to 1812, text 1993.
However, it appears that the correct name of the master silversmith with the master's mark IH on either side of a tree should be Johannes Horstman.
Johannes Horstman (1721-1804) was the son of Jan Horstman(occupation baker) and Alida Bruyn, who married in 1717.
In 1758, Johannes Horstman became a citizen of the city of Amsterdam and presumably shortly thereafter completed his master's examination at the Amsterdam silversmiths' guild. He was productive as a tableware maker, making items such as trays, bread baskets, candy trays, and tea sets. He ceased his trade between 1790 and 1795.
