While I’m on the subject of converted industrial buildings, I walked past the old Allen & Hanburys building just to the west of the Cambridge Heath Road a week or so ago. It’s another old established East End firm, bought up in 1958 by GlaxoSmithKline, with the factory closed some time in the 1960s. It was founded by a Welsh Quaker, Silvanus Bevan, in 1715. The eponymous William Allen joined the firm in 1792 and his second wife was a Hanbury. They made those blackcurrant pastilles in a tin box which used to be sold under the name Allenburys, but are now made in Switzerland; also, cod liver oil and weighing scales:-
People forget that London was full of small, and larger, scale manufacturing.
