Probably recognition of the designs in the later images is feasible but getting some of the earlier ones will not be so easy. Perhaps someone will recognise a worker. I should think that at least two glassworks are covered but as the report was prepared by

It woud seem likely to have been one of those, but the report states 8 glassworks handblowing lead crystal remain in 1946, who could the others be? Webbs, Haden, Mullet & Haden, Amblecote and Brierley Hill? The reason it is only Stourbridge people was that the original instruction was to limit the report to that region. It was the team that decided it need to cover the whole country! I am of course irritated that they did not address Edinburgh Crystal directly but they did recommend "...a design research and training centre at Edinburgh." that had already been proposed by then. Which of course we all know was set up and highly successful it is too. Colin Terris for example!
