An important Thameside engineering firm which became a major supplier to the Royal Navy having developed the oscillating engine for paddle steamers, the trunk engine for propeller steamers and the wood stern propeller-shaft bearing. It supplied nearly one hundred small trunk engines for small gunboats during the Crimean War. Several of these engines were reused in small merchant vessels, one of which was the Xantho. This engine is the only surviving Penn trunk engine which can be seen.
