The snow having vanished, for now, I can check that what I built while confined indoors does actually fit. Troga Mill sits alongside it's waterwheel nicely.
(onlycrackingjob is likely to know why it's Troga mill)
The wheel isn't attached to the mill: it was easier to make it work separately.
I may add some extra "stonework" over the brick section (where new machinery was added, in backstory, but actually to be absolutely waterproof) to produce a bit more "curve" to better visually marry the wheel to the mill.
