Here is an antique silver plated julep strainer marked “1847 Rogers Bros. A1”. It measures 5 and 3/4ths inches in length and the bowl measures approximately 2 and 3/4ths inches wide. The pattern is a classic “back tipped” design.
This strainer, with the open star in the handle, was featured in the 1886-87 Meriden Britannia Catalog and was called the “Star Julep Strainer” in that catalog. The photo shows this strainer on that catalog page.
Harry Johnson, in his 1888 book, “The New and Improved Illustrated Bartender’s Manual” states that the strainer should be placed in the drink and served (you can read more about this in my blog post mentioned below).
