Parker colored Bakelite pens

Today's second under-our-noses discovery was in another issue of Parkergrams, dated September 1918, also in the PCA Library. Key passage:

" . . .we are now making the Bakelite in a translucent barrel in two or three very beautiful colors. It has been practically impossible for use to get any more of the Ivorine [this casein-based plastic was imported from France], so we have developed two or three colors in the Bakelite. A very pretty shade of green, for instance, one or two shades in red and pink that are really very beautiful."

Green and pink Bakelite Parker eyedropper-fillers . . . has anyone found one?  I'll have to review my photos of the Parker Archives -- perhaps some of these have been sitting there, misidentified as Ivorines.
