I believe this mill SE2019 : Ledgard Bridge Mill off Back Station Road, Mirfield (SE201194) is Ledgard Bridge Mills, formerly George Lyles and Co. Until about 1981 this mill contained a rare pusher compounded beam engine. This was taken out on the pretext that the mills were to be demolished. They are now housing!
