While in Gas Street last night I was having a tour round Google Earth and found that the time clock allowed me to go back to 1945.
You can see clearly the duplicated locks at Smethwick. After hunting round I found quite a few canals that are no longer here, such as, the Toll End, the canal that extended out from the Cambrian Wharf and lots of arms now filled in.
The other interesting place to visit in 1945 is London, seeing all the docks full of ships.
