David and Sampson are beam engines that blew air into the Lilleshall Company's blast furnaces at Priorslee. Built in 1851 by Murdock Aitken and Company of Glasgow they were in regular use until 1900 and standby engines until 1952. They were moved to the Museum and reconstructed in 1971.

The Lilleshall Company was the largest industrial concern in the northern half of the East Shropshire Coalfield for over 150 years, and once had extensive iron and steel works, engineering works, coalmines, brickworks and a private railway network in and around the Oakengates, St. George’s and Donnington Wood areas.
