Apparently Potts only set up in 1833 so a bit late for the building of the stables in 1789.
I'll have to brave the pigeons again and look for any other plates.
There is another clock on the main house which has run in recent memory and on another tower is an indicating wind vane, I.e. it shows the wind direction on a dial lower down the tower.
Apparently there is a boiler in the cellars which is identical to Titanics boilers. Cant wait to have a look at that.
