It turns out that the Phillips was originally a deep red, not black like I had assumed. The fork steerer tube gives a pretty clear indication that this was the original color. It seems, in fact, that the base coat was black with the red on top, which creates a rather striking and rich red. This could mean that the bike is not pre-war, since most specimens from the 1920s and 1930s seem to have been black. However, at least one pre-war Phillips that I know of had a rather more striking original color scheme. In other words, the color doesn't do much to help date the bike, but it certainly did come as a surprise to me.
Also, I've managed to scrape the yellow paint off the head badge. This will be black, red, and gold when finished, like this one.
