Leroof - the sideways BW is another logo for Bing - in this case it is Bing Werke - your earlier station with the GBN metal identifier between the windows is also Bing and it stands for Gebruder Bing Nurnberg. Bing went out of business in 1933 so anything Bing will be pre-war.
As for the bridge span it is part of the bridge assembly 10/655/0 which was made in various forms from 1912-1929. The BW logo and all litho treatment would date it from sometime in the 1920's.
The model number for the large Bing station in your first post is 7065. It was made from 1909-1922. The colors would suggest it is an early example - probably pre-1920.
You indicated the stations in your first post looked like they had candle holders and no electric sockets. If that is true for the Fandor station then my references indicate the Fandor station is 2047/1 and the estimated years of manufacture are 1926-1930.
The footbridge bears a strong resemblance to Bing 60/637 but the semaphores are not spaced the same distance apart as the one I have illustrated in the 1928 catalog.
