Pots or inkwells (Fig. 24) commonly used in the English Channel by the Cornish and Devon crab fleets are rapidly becoming the most important method used for catching brown crab in Scottish waters, in terms of number of pots used by each vessel and the tonnage removed. The construction of these pots has changed from using natural materials such as cane to plastic piping frames with a netting cover with plastic `bucket' entrance with a heavy plastic matrix base. The stanchions, base and top area are protected with either rope or old car tyre.

The first major iron truss with pin connections was built in the USA in 1859, and the earliest iron cantilever in Germany in 1867, over the Main at Hassfurt. Figure 11 Bollman Bridge (c 1869), Savage, Maryland (USA). This pre-restoration photograph shows the paired stanchions located at mid-span that support the anchorage block where the radiating suspension stays all meet in pinned connection. The octagonal profile of the vertical and horizontal compression members was a design motif of Wendel Bollman, the bridge's designer. He, along with Albert Fink, who designed a similar type of structure known as the Fink truss, motivated the chief engineer of the Baltimore & Ohio Railroad, Benjamin Henry Latrobe III, to use iron bridges exclusively for the system's major
