Very briefly:
Floor 6 Mill
The original mill was what is now the centre section and was constructed around 1863-4.
Power for this was provided by a 20hp steam engine by Fawcett, Preston & Co. of Liverpool made in 1861 in the centre bay of the engine house built at right angles to the north wall. The east bay contained the boiler – a 20ft x 5ft Cornish type by John Latham of Chester in 1864. The west bay contained a fitting shop. The discrepancy in the dates is curious, but may only mean that the engine was a stock item.
The first extension to the mill was in 1888/89 on the west end, using materials from the Alabama Floor 2 Mill. A second extension followed in 1894 this time on the east end. A new Lancashire type boiler was now fitted in the old fitting shop, but whether this superceded or supplemented the Cornish one is hard to say.
The last change was electrification in 1913-15 when the whole of the steam plant was removed and electric motors installed in the old engine room.
The uphaulage incline from Floor 3 was in place on the 1901 OS map, but no head building is shown. The next edition of ca 1912 or so shows the building in place. A copy of the 1901 map annotated by the Diffwys company labels it as “New Electric Hauler”

The map is the territory - especially in chain scale.
