Abstract
Based on a new model introduced in 1843, this all brass instrument rests on a tripod, with the limb moving on the trunnions and supporting the body-tube and stage. The model served as the basis of the company's instrument design through the rest of the century. It comes with a mahogany carrying case and accessories. Signed: Powell & Lealand, 4. Seymour Place, Euston Square, London. 1847.
