I have since verified that it is a piece of Duncan & Miller.

I often see tumblers pressed in the honeycombed Georgian pattern. A number of companies produced these tumblers and it is far beyond my ability to recognize whose is what.
I came across this pitcher recently and was struck by its rich colour. I have never before seen a pitcher in this pattern.
I haven’t had any luck identifying it, but have seen a similar item online, in a different colour, identified as a piece by Duncan & Miller. Would love to know definitively, if anyone has any info.
