NOTE: Speculated as made by Boston and Sandwich Glass Company.
Note: Sid Lethbridge 2019: Any assignment to B&S should be treated as speculative because there is no documentation to back it up. Many of the pattern assignments to Boston & Sandwich were made during the period where everything that could not be documented to Bakewell, Pears and McKee was automatically B&S. We know that there were about thirty companies making tableware during the flint era but only a handful get credit for most of the production.
