This April 16, 1949, article in the Portland Press Herald highlighted critic complaints about several new sedan delivery wagons purchased for use as police vehicles. There was some concern that these new patrol vehicles would be unable to catch modern hot rods. In response, the police chief reminded his critics that this was an experiment.
You will note that there is a black blotch covering a small portion of the second part of the article, but I don’t think anything important is lost with it there.
