Depends... probably not the answer you want, but that's the way it is. 
In the 1920s, many brick buildings would be less than 40 years old - depending on location. Brick structures would most likely be present earlier in larger urban areas than in smaller or semi-rural areas. In either case, the DPM series seems to represent late Victorian era structures well, so that would be my starting assumption.
Then depending on location, the weathering could be dark, light, so anything else. If the buildings are in a heavily industrialized area, they may be blackened by soot. Other sources of weathering include airborne dirt and dust, rain, and the bricks and mortar deteriorating. This last one may be less important in a "younger" building.
Hope that helps.
