Whilst their father had specialized in drawing instruments, Elliott Bros offered a wide range of mathematical, optical and philosophical apparatus. The firm began using the signature "Elliott Bros London" in 1873 and "Elliott Bros (London) Ltd" in 1916, who appear to have discontinued producing surveying instruments around 1914-1918 and began to focus on developing electrical equipment.  We join : Brass surveyor's theodolite.
