It looks similar to regal red comice https://www.dalival.com/poires/regal-red-comice-en/. See the slightly lighter striations running through the pear. How does it taste? See this thread to try to identify it further https://growingfruit.org/t/what-pears-will-you-grow-this-year/20412 . Consider grafting backups and giving scion cuttings away to friends when you prune it. It is becoming rare unfortunately like most red pears. They are falling out of favor. In my opinion it is a little dark for red anjou and does not have enough vertical striping as shown below. Red anjou is a great looking pear but not as pretty as the pear you are growing https://produce/pears/red-anjou-pears
Miller did become part of Starks as you say https://www.starkbros.com/about/miller-nurseries
Fortunately i hsve the advantage of having read this question before and know exactly how to identify your pear based off the work @hambone @BobVance did last time which is to get your hands on an old catalog https://growingfruit.org/t/searching-for-millers-nursery-catalog-from-1990s/5617
