Eye dropper Rapidograph?

[Catpaws]

I have a Rapidograph from my college days but seem to have lost the ink reservoir. So I looked online for a replacement or a donor pen. But then I thought maybe I could plug up the vent holes in the barrel and eyedropper it. Has anyone done this? Is it a bad idea? Should I just keep the pen for spare parts and get a new one? The weight moves in the nib unit moves so its not clogged.

Thanks!

I think you should try to trace a reservoir (is the Rapidograph the one that was using cartridge like reservoirs?)

The Rapidograph barrels were rather fragile, and frankly I'm unsure that you would be able to screw them on securely enough to avoid leakage in eyedropper, also from the bottom finial (which was also screw on, depending on the model you had).

Leave the nib unit in water for a while to be sure it's clean.
I've used Rapidographs with fountain pen ink at length, it might be worth a try, but I suspect finding the right cartridge would be best.

Thanks. I think for now I will keep looking for the reservoir.  Can't do much harm that way.

I'd suggest you search for "Rapidograph tip", something may come up reasonably cheap with the cartridge attached...
