k = kilo - not someones name - thus lower case
W = Watts - as in James Watt - so capitals
h - hours - as per kilo.

so its kWh

Newton metres = Nm

etc etc

guydewdney - my first thoughts were it was back to front, but looking at the again I convinced myself it was an overshot and missing the raised water delivery channel. Where as if it was reversed it would appear to be mid shot and thus have even less power... ?
There has certainly been quite a bit of 'landscaping' of the stone work around it, so you may be correct.

The locals believe it was for a small saw mill - which I have my doubts about as it is within the grounds of country hall, off which this is in the garden of the gate house. Ive checked the local history records and no mention of it. So it could even of been imported to the location at some stage as you say for a feature ...

Anyone care to take a stab at a cost to bring a wheel on line here ? Assume its 100 mtrs to the house.
