Footnotes
A fine example of one of the finest model makers of the 20th century. Care of construction and painstaking attention to detail are evident throughout. The first example of this model was commissioned for the Windermere Steamboat Museum collection.
The steam launch Bat was built by Brockbank of Windermere to the design of her owner, Alfred Sladen in 1891. In 1904 she was used by Isaac Story and Jack Kitchen to conduct experiments in early radio control on the Lake, where she was steamed around the northern end with only a stoker on board. It is believed the first example of a vessel being controlled by radio. Found derelict at Bowness in 1966, she was rebuilt and now can be found in the Windermere Jetty, Museum of Boats, Steam and Stories.
