They are a range of spanners (wrenches) used mainly in the British aircraft industry in the 1930's to the 1960's.
There are several types of spanners, commonly categorized into two main groups: adjustable spanners and fixed spanners. Adjustable spanners, like the crescent wrench, allow for varying sizes of nuts and bolts, while fixed spanners, such as open-end and box-end wrenches, have a specific size. Other types include socket wrenches, torque wrenches, and combination wrenches, each designed for specific applications. Overall, the variety of spanners available caters to different fastening needs in mechanical and construction tasks.
