Can anyone recognise the make of this pen please?

This was given to me so I have no idea of its age etc. I can't see any brand names on the knib (just says Radium), the barrel or the clip. It's fairly weighty and I'd like to be able to restore the missing bit on the end of the cap and also buy the right size cartridges so I can use it!

It looks like it's triangular.  I'm only aware of the Omas 360 that is a triangular fountain pen.  Close ups of things like the nib, clip, and cap finial are helpful for identification.  Are there any markings on the section trim ring?

I think it's the way the light is catching it that makes it look triangular. It's a round pen. No markings that I can see on the trim, other than an abstract pattern.

Not sure of the brand but it is highly likely that the cartridge with be an International short.

Can you take a picture of the inside of the section?

My guesses are this is a Ted Lapidus model, and that the nib reads iridium, not radium (would otherwise be a dangerous pen... 😁). These pens are made in Germany (although they often are marked as Ted Lapidus Paris). Ted Lapidus also sells cologne

I think you're right.  I've now seen this particular trompe l'oeil on a number of pens I know to have round cross-sections.
