This has a Dominick & Haff mark, but I'm interested in knowing the date of its manufacture and, if possible, the name of the pattern. This pepper shaker (I assume it's the pepper because there is a "P" on the bottom?) was probably my great-grandmother's. In addition to the hallmark the numbers 181 (I think) appear, as well as the "P" mentioned above.) There is also an "M" on the lid (see photo).
Hope I posted the photos correctly -- They were right side up when I uploaded them, but they appear sideway here -- my apologies!
Thank you.
