Scale: Unknown. A model depicting part of the process of manufacturing a common anchor, made entirely in steel. The model shows how an arm is made. All surfaces are highly polished. Twelve long, tapering, bars of steel are bound together by two steel hoops. The bars are flat in section, arranged in a single stack, are cut diagonally at their wider, bound ends, and the bars become progressively wider, in relation to one another, until the sixth and seventh bars, before becoming narrow again. This arrangement produces a bound shape roughly circular in section. The bars converge and taper to a point at which they are welded together, the resulting single bar of steel, at this point square in section, tapers further to a rounded point. The tapered end gradually becomes circular, rather than square, in section.
