I'm relying here on the research of Peter Bone presented in the Journal of the Glass Association Vol 8 (2008).
The Stourbridge Flint Glass Works are down as connected to William Maginnis then John Williams, then from the late 1830s to early 1840s, a partnership of Atherton & Buckley. William Atherton is declared bankrupt in 1843 and Percival Vickers take over the site until about 1875. I assume it was their secondary site as I believe the one on Jersey Street was custom built at the time of founding in 1844.
These glass houses could be erected pretty quickly. For example Molineaux Webb leased land on Dec 26th 1826 and started production on June 18th 1827.
The Webbs of Stourbridge were never involved in the Manchester glass industry as far as I know so the great glass website has mixed up Thomas Webb & Sons of Varley Street Ancoats with other companies. Thomas Webb & Sons morphed into Webb Brothers. Looks like the factory was only active for 10 years or so.
The Prussia Street Glass Works was run by Ker & Webb, then Andrew Ker, then briefly Samuel Ralphs, then James Bridge & Co, then taken over by Butterworths, all in a short period between c1870 and 1900
