Check out the following pics - side by comparison with an original cap, and one that I thought for years was an NOS cap, but could be the early Trim Parts cap - it has part # 3901314, a secondary number of 3874640 and a "CMD" logo (Trim ?); the original has two numbers, 3945461, and a 27047, with a crest logo with "CM" cast into it, with the outline of what appears to be a state (WI or IL ?). Hard to make out even under magnification, but as you can see it has some age and a little paint problem in the center. Both backgrounds surrounding the Bowtie are "pebbled" as Ed mentioned, colors are identical as far as I can see.
Good luck in your search - these things are getting harder to find.
