Scale: Unknown. A model depicting part of the process of manufacturing a scarph chock anchor, made entirely of iron. The model shows a roughly rectangular lump of iron with several smooth flattened faces, one of which is angled. Attached to this, and extending from it, is a long, tapering, four-sided bar. The bar is slightly irregular in shape with a slight kink or shoulder at the wider end and terminates in a point at the other. On the smooth underside part '3' is stamped and a number '1' is stamped on the tapered square section. The model is one of a series of nine anchor models showing various designs for use between the butts of the scarphs.
