Here's the building where my employer is on the ground floor, though the postcard is from the 30s (I think) before the stations were here. This view shows the east wall with main entrance and the south wall, with another entrance.

The large rectangular windows on the ground floor are all radio stations now.
This is the back side of the building (north wall with indent, and west wall), it's not a solid block. The first three floors are solid, then the wings as seen in this photo. They are also plain brick, unlike the east and south walls.

Here is a site that has tons of pictures of Quincy, including the Lincoln-Douglas building and the Newcomb Hotel (which I mentioned looks EXACTLY like one of the buildings you did, except it's only five stories).

They'll work fine. You can't really see them all that well from the railroad anyway.
