Sir Nikel Gresley, the chief engineer of the London & North Eastern Railway (LNER), designed the A4 Pacific class 'Mallard'. On Sunday 3 July 1938, Mallard reached a speed of 126 mph on a straight stretch of track between Grantham and Peterborough, achieving a new wold speed record for steam locomotives, which remains unbrocken to this day.

This Mallard train is made from lead-free pewter and is supplied on a quality key-chain.
