Description

This is an example based on the Lister frame, made by Powell & Lealand and retailed by Carpenter. It is known as the \\\”Student\\\” or \\\”Iron\\\” as the stem and frame are made of black iron. Although most of these examples only have coarse focusing, this one also has fine focusing. The focusing screw activates a pinion which acts on a rack which is built inside the body tube itself. Ross and, especially, Dancer, used the same focusing system in their early models, switching to the rack and pinion system later. It is uncertain when Hugh Powell made his first example, but it is considered that this could have been around 1838-40 and his last example dates from 1911. The lens has a pre-RMS thread so must be before 1848.
