Charles Burrell & Sons of Thetford were the main suppliers of steam engines to travelling showmen and circus companies. 

In the early part of the 20th century, the scenic rides (meant for adults and children who could sit on horses or carriages that would move in circles) meant it needed power to operate the machine as well to lit up the dark nights. So Burrell’s team provided the electricity needed to run the operation with the help of an auxiliary dynamo.

About 43 of such engines were built out of which only 13 or 14 survive after heavy restoration. Being associated with different types of shows, these machines were nick-named Scenic Showmans. Dolphin was the name of one such machine.
