Here is a sterling silver julep strainer marked “Sterling 26” preceded by a hallmark which I have not been able to decipher. The strainer measures 5 and 1/2 inches long; the bowl is 2 and 3/4 inches wide.
This strainer has a scalloped shell shaped bowl and a star cut-out in the handle for hanging.
The hole placement and shape on scallop shell shaped julep strainers varies by manufacturer….some holes are oval, some diamond and some cross shape. This strainer has round holes. In my experience, round holes placed as on this strainer are found on strainers manufactured by Simpson, Hall, Miller and usually marked with Wm. Rogers, one of their trademarks. The last photo shows this strainer in between two other Simpson, Hall, Miller strainers which are silver plated. As you can see, the holes and star cut- outs are exactly the same. Simpson, Hall, Miller did manufacture sterling items. The hallmark on the handle preceding the word “Sterling” doesn’t appear to be the SHM hallmark. SHM joined International Silver in 1898 and this could be one of the IS sterling marks. It was double stamped, which makes it even harder to determine. The “26” could be a pattern number.
