I guess bouncing it off the Corning Museum folk would be the next step.
As to Hobbs etc, Ivo's Glass Fact file, gives Wheeling as the location and the name changes of the company. Perhaps Wheeling gets used when items span name changes. It is quite common to get glassworks names and the company name confused, particularly in older books, but sometimes because items were sometimes marked with one or the other of the two names and no-one knows the connection. Interestingly that in 1910 the Pottery Gazette list Tomey & Son, Tay Glass Works as the only glassworks in Perth. Yet at that time the North British Glassworks was also there run by John Moncrieff Ltd who also owned Tomey and the Tay glassworks - I have never been able to find out why both companies were kept in existence, presumably just business instruments. On the web you will rarely find North British Glassworks linked to Moncrieff because their target balls, only, were marked N B Glassworks and almost everything else as Moncrieff, Tomey or Todd.
