History
Designed by Matthew Murray, and made by Fenton, Murray and Wood of Holbeck, Leeds, it is one of only two of the type to survive;[3] the other is located at The Henry Ford, Michigan, United States.[4]
The single-cylinder engine was used by John Bradley & Co of Stourbridge from 1805 until 1931, and by N. Hingley & Sons Ltd of Netherton from 1931 until 1961, when it was acquired by Birmingham City Council for their science museum.[5]
