I don't know anything about the quay near the rifle ranges, but i can remember what was left of the old quay house and the quay along at bit towards parkgate, i went for a walk that way a couple of years ago and was a bit put out that it had all deteriorated so much in the 20 years since i had last walked in the area !.
Something else i noticed some years back now is that the railings (or what was left of them) on the wall at parkgate had vanished, they where at the old Quay Pub
end, they used to be there in the 1980's !!.
Another bit of History
that has been lost !.
