Goldberg’s Bagels in West Hartford has a pork roll sandwich – I posted a thread about it a while back. There was some debate about whether it was the genuine Taylor product; I confirmed with them that it was. It just looked different because they slice it super thin compared to how it’s normally done (and thin meats are the standard here).
I’ve also been able to find the Taylor brand at some ShopRites. It definitely has a presence in CT.
