I've got some Kullock parts for a 51 DJ Vac ("Demonstrator"). As I had one of them, the remaining parts (cap, feed, collector, nib, ring) were already available for me. I still keep the original "plastics" but I am currently having fun with the "new" pen. When assembling everything, one of the iridium pellets pop off (and it was one of the gold nibs), so I had to clean some of the Super 21 spare nibs I have (steel / octanium) to finish the job.
Another pen I got is a Parker 20 1/2 button filler (Jack Knife). It doesn't have a pressure bar, and the ones I got are slightly short for it. I am not really certain of which type of bar they have, or where they rest when pressing the button .
The third one (and I haven't yet started to work on it) is a Skyline (burgundy, plastic cap). Seems to be in a nice condition.
Rgds.
