Solid cast brass knob dating from at least early 19th Century, in a form and style note seen before: first is the flattened S-shape on top of a turned and footed shank…then there is the little star-topped screw that holds the knob by threading into the spindle…and the spindle itself is round rather than square, and had something attached at the other end, so perhaps this was a knob for a special lock such as on a safe or money chest. At any rate, it is a true collector item in fine condition….
