Old Pumping Station Prince of Wales dock

This is the old pumping station at the Prince of Wales dock.
Update
Had to pop out mid posting as we had an emergency. All resolved.

The Prince of Wales dock was a dry dock - I remember as a child being taken on a tour of the North Carr (an Nothern Lighthouse Board lightship) when it was here for repairs. The pumping station is a listed building which I think is used by Forth Ports Authority as an admin building now.
