The article in the British Architect is the source of a more detailed description of the work itself:
“The design comprises four sections-Forging-Grinding Hafting and Fitting (and finishing of scissors). In the first section commencing with the ‘forgers’ the first figure appears plunging the hot scissors into the hardening trough. The next fig. 2 is forging scissors and fig.3 is at the bellows heating the iron and figs 4 and 5 are the maker or ‘smith’ and the ‘striker’ forging table knives. Fig. 6 is bringing a bundle of steel into the smithy.”
This is where the first section ends; these divisions make use of a doorway to indicate movement to a different workshop where the next process is going on.
