Scale: Unknown. A model depicting the method of manufacturing a common anchor, 1829, and made entirely in iron. The model shows a tapering bundle of irregularly sized and shaped iron rods, square in section, and bound with two square, smooth-faced iron hoops. The bundle tapers to a long rod, also square in section, and itself tapering to a point. The rod is welded to the bundle and gives to impression of being formed from a single piece of iron. The surfaces of the bundle of rods appears to be finished or painted black. The numbers "6" have been stamped on each of the square hoops,"5" on each face of the bundles and "1" on the square section of the tapering rod.
