An exquisite Steamcraft model,the 4-6-0 GWR KING CLASS EXPRESS was built by David Taylor himself . He ran it intermittently and between runs it stood in a glass box in his office. I am honored to own this fine example. it is the 3rd of his exquisite products in my collection.
The locomotive is gas fired with double acting cylinders.
