Parker started making the "Parker Cartridge Pencil" which was way ahead of it's time when released in the late 60's. A simple cartridge the same size as the ball point cartridge would be inserted in any push button Parker ball point to convert it into a pencil. Early metal ones used 0.04 inch leads which are no longer available although you can use 0.9mm ones which are just a shade loose but workable. The all metal ones could be removed, replaced etc just like a ball point cartridge.
The later plastic ones made in Japan used a more modern 0.5mm lead but tended to be a bit more fiddly in that they have an O ring at the nib end that makes removal difficult without damaging the ring.
It seems a really neat idea, and they work really well ... I still use 2 of the old metal ones in Parker 45 ball point bodies ...

That's very interesting, thank you
I didn't know there was an easily replacable version of any Parker pencil cartridge. It would be funny/interesting to change the pen filling to a pencil cartridge from time to time. As I see it was in that thicker size only (1,1 mm), so it's a bit like the earlier version of mechanical pencils, propelling pencil (I actually found one made by Koh-I-Noor).
All the Jotter mechanical pencils I found have plastic cartridges inside them, I posted a photo about both 45 and classic ones' cartridges earlier, opened up.
The second picture at the top of the post shows a pretty clear "45" engraving on the cap, so I'm not sure what is confusing about that.
Liuna - the last version of the P45 family in the 2000's had an altered clip and a rounded black jewel on the top of the clip, referred to as a cabochon. You can still see this style sold on Amazon as the Parker Galaxy made in India by Luxor.
Yeah, I can see it, but I didn't really realize from the photos it was a cabochon at first (found similiar ones earlier when browsing photos of 45 pens and pencils. It was a bit hard to tell from the view the photos were taken (official ones). They look very nice
Now I got to be somewhat fond of the metallic blue, "Waterloo" named color version... (Are those metallic ones are full metal like flighters? I'm not sure.)
