There is a dearth of information on Chiltons in general. There are some ads about, but the only catalog I know of is the 1937 Wingflow catalog (although I've heard that there are two versions of this).
Rick Krantz has worked out the colors for the Long Island Chilton's, although some anomalies remain. Many of the Long Island Chilton's have a two or three digit number on the end of the blind cap. The last number is usually the size, and the first (or first and second) number represents the color.
The one that you describe sounds like a black/bronze. I've forgotten the number associated with that color.
There are a number of colors missing on the site that you linked to, such as bronze/cream, burgundy with black veins, royal blue Wingflow, and there's even a bright blue pen that may or may not be a late Wingflow. Edit: There is also the Chilton "Clown" or harlequin, which AFAIK is unique to Chilton, and a Persian celluloid that's seen in some Waterman pens. I'm still probably forgetting some.
Incidentally, one of the pens pictured on the site that you linked to was probably not a Chilton, strictly speaking. The one that says "Private Brand" was most likely a Seth Crocker. The end cap has a slightly different shape, and that's not one of the plastics Chilton used. The Seth Crocker's are interesting, because it's a brand formed by Seth Chilton Crocker at a point where he was no longer involved with the running of the Chilton Pen Company. Many of the Seth Crocker pens have analogs in the Chilton line, probably due to the close relationship of the companies (both were founded by the same man) but that particular plastic was unique to Seth Crocker, as far as I know.
