Great Uncle Fred Higgins played rugby league in the Fifties for Widnes, England and Great Britain. He also ran a haulage company. My Grandad helped him build a brick workshop in his yard with heavy metal purlins bought from an old military base, hoisted by muscle power (using a guy derrick, artfully depicted in woodcut here), and covered with asbestos sheeting. People knew how to do all sorts of stuff in those days. Apart from the asbestos roof bit. That wasn't such a good idea.
