Thanks to everyone for comments and info about C/Fs. I've put together a table of everything I know about C/Fs and attached a jpg (not sure how to attach an excel file.....).
I will update it as I get more info. And if can find the time I might turn it into an article with photos!

Here are the column titles with some explanations.
Model - Model Number
Barrel Color
Barrel Section Color Combo - Barrel Color followed by section color on individual pens that I have or have seen.
Nib - 14k, SS = unmarked stainless (or something like it), some SS have either number 42 or 43 stamped on them, and ads list "merido metal" which I assume is the same as what I am calling SS
Shoulders - these are the metal inlays on the section, some folks call them inlays, others call them wings. The original patent contains the following: "...the member 26, can be inserted in the mold and the section molded to to. At if forward end member 26 includes a yoke 27 and extending rearwardly are wings 28 united at the ends by a band 29". So according to the patent the inlay is called a member. I thing shoulders or wings are a bit more pc for today than the word "member".
Cap - gold or g/f both refer to gold-filled (g/f?, some of the g/f and chrome caps have vertical lines
Clip - gold means g/f
- smooth top means the top of the clip is smooth
= globe top means the top of the clip has a globe-like imprint
- some C/C pens have a closed-clip (no opening like the C/Fs) with a "Waterman USA" imprint on the clip
- some C/C pens have a closed-clip with no imprint and plastic 'jewel' at the top.
- the variations of these pen in circulation is large and there are few with chalk marks and no ads that I am aware of...
