I have a vintage Yard-o-Led Corinthian and aside from being beautiful, it writes well, until it doesn't.
No hard starts but the flow gets less and less and then goes dry. I open it up and there's plenty of ink in the converter. I can push the ink up using the piston and then it writes well, until it doesn't.
I suspect it's the converter since the nib does work.
Should I just replace the converter? Or do you think this might need real repairs?
