Took a closer look at my pens sitting on the shelf and realized my red-bodied pen (looks like the same red plastic as a J pen) is actually a dipless desk pen rather than a fountain desk pen. It has a black taper.
The only dipless bases I'm aware of are the 407 series (the ones with the metal clip) and the 444 series with the glass bases. (the "series" includes variations like the doubles 427 and 484)
Would this have gone in one of the red 444 bases? Or was there something else?
I know with the fountain desk pens they had different colored bases (like the eight-ball) and pens to match. I never realized until now that possibly the colored 444 bases might also have had matching pens. I guess because all the Dip-less pens I see have black bodies and either clear, black or red tapers. This was the first colored-barrel Dip-less I've noticed.
I have white, green, grey, black and red 444 bases. I've only ever seen a red Dip-less pen. Anyone seen any other colors? Would love a white one!
