Reference entry on Pacific Plate Works, thought to be related to Haynes & Lawton and operating as late as circa 1910. Here is a broth spoon with mark "H & L S Co" made for what appears to be the Hotel Alexandria Los Angeles (c.1905). Previously, an item of china for this hotel was found in Canada with marks for the Union Porcelain Works (UPW) of Greenpoint New York (thought to have exited the decorated commercial china market around this time). That could well have been the last order for this important pioneer firm. If this is a Haynes & Lawton mark, we may be looking at one of their final projects also.
