For the Tyne Steam Packet Co. This engine was very similar to a standard 20 horse land crank engine, and was virtually identical to the engine fitted in the Navy boat Congo [see Portfolio 5/1228]; the drawings for both engines were kept in the same book. The engine is listed under "Tyne" in the Drawing Office Index. Note that Boulton Watt & Co. later built 20 horse side lever engines for a steam barge also named Eagle [see Portfolio 5/1263].
