Waterman's CF Refill

BALLPOINT REFILLS FOR OLDER AND LATER CFs AND OTHER WATERMAN's BALLPOINTS.   I had a batch of those funky old refills with the flared back ends made. These fit BOTH of the Waterman's CF ballpoint releases from the 50s and the ones from the 80s. They fit most of the other older Waterman's ballpoints shown below, the ones with the long monster springs. And they fit the newer 80s release CFs with the fold-over rube Goldberg holders for the fillers (one of these pens is shown at the bottom of the first photo). They fit a lot of other early Waterman's ballpoints that aren't shown below; If yours has a flared back end on the refill and the monster spring, these will fit. The second photo shows typical Waterman's older non-CF ballpoints that these fit as well as a later "Classic" CF released in the 80s. The last photo shows the dimensions of the original filler that these replace. Black ink w/ a tungsten carbide ball. 

The Cartier refills come in black or blue.  The length of the refill, including the tip is 3.7315". The length of the refill without the tip is 3.368 inches. The diameter of the tip is 0.058".
