Surveying and Drawing Instruments
A trade catalogue of surveying and drawing instruments issued in 1911 by C.F. Casella & Co., Ltd., a London instrument maker, for surveyors, draughtsmen and engineers. Its pages show precise metal instruments drawn in fine black line on cream paper, including map measurers, proportional dividers, spring bows and a transit theodolite, which a designer might borrow for technical diagram detail and tool-catalogue layout.
