flying free, I’ve no idea if Bill Swingewood and W.H. Swingewood are one and the same but here is a more complete quote from page 452 of Jason Ellis’s book:
“In common with so many other businesses, L. & S. Hingley struggled through the depression years and the period of the Second World war. The firm survived until 1948 when the glassworks was advertised for sale. A buyer was promptly found in the firm of W.H. Swingewood & Co. Ltd. that had operated in a small way in Dial Lane for the previous twelve months. The directors were Mr H.A. Marler and Mrs A.E. Marler, both of whom were local publicans. H.A. Marler ran the Bulls Head in Wollaston and A.E. Marler ran the Vine in Blackheath. The old twelve-pot furnace had not been used since the time of the First World War and as part of a modernisation programme the cone and furnace were demolished on 28th January 1949. A new glasshouse was built and part of the old premises was adapted as a decorating shop. It is not known how long W.H. Swingewood and Co. Ltd. was in business, but some of the original buildings are still standing today” - [written for publication in 2000].
I see from Google maps that, at DY8 4AZ, adjacent to the Red House Glass Cone, and between Bridge Street and the canal running parallel, is a site with light industrial buildings. This is presumably the site of the Albert Glassworks and the site occupied by the W.H. Swingewood buildings. I must have a poke around the area the next time I visit Broadfield House and the Red House Glass Cone.
