Glen — Your either / or doesn't cover all possibilities, so your question is difficult to answer.
What happened, according to Baker & Crowe (sourcing from Baker's earlier
PYREX — 60 Years of Design) and Thompson was:-
1870 — James Angus died, so their Trimdon Street factory became Henry Greener, The Wear Flint Glass Works.1873 — Factory relocated to a larger site at Millfield.1882 — Greener died, and the company came close to bankruptcy.1885 — James Augustus Jobling, principal creditor, took over.c. 1885 — name change to Greener & Co., The Wear Flint Glass Works.1921 — name change to James A. Jobling & Co. Ltd., The Wear Flint Glass Works.c. 1928 — name change to James A. Jobling & Co. Ltd., Wear Glass Works.Note that Greener & Co. probably acquired limited liability status before 1921.
Anyway, Glen, once the factory had set up at Millfield in 1873, it was one continuous operation until the recent closure — the 1921 and 1928 name changes were purely cosmetic.
Does that help?
