From my 70s childhood badge collection. The product is an old enamel train badge featuring the LNER A4 Pacific No 4468 'Mallard' from 1938, which holds a record for the fastest steam train in the world. This hardware railwayana collectable serves as a emblematic piece of railwayana memorabilia from the LNER era, making it a unique and valuable item for transportation collectable enthusiasts. The badge showcases the rich history and significance of the British railway industry, particularly during the vintage era of steam trains.
