SWAN 1920s or so

I bought this from Andy's Pens.
I liked the idea of an eyedropper as those fillers have to be disassembled for repair.
Due to its age I hoped to find some more obscure elements, and was not disappointed.

In case you can't read what is written on the screenshot, it says the following:
86.64% Osmium
2% Iridium
9.57% Platinum
I can't remember the reason for the negative figure with gold and
3.64% Rhodium

So this is where I stop, there is Iridium in this nib, but mostly there is no iridium it is just a generic term.

However, iridium has an interesting aspect, it is present in significant quantities in the KT layer
