Mike,
That is La Brugeoise and Solvay, both companies still exist today. La Brugeoise is today part of Bombardier. Just before the war they constructed trains, trams, steel bridges, parts for breweries (is that why they were bombed ?

).
Solvay was a chemical plant and you can find more on the company over here :

Hope this helps a little...
Best from Johan
