Dear Onoto Guru's,
I have a metal Onoto that needs service, but the plunger is frozen (see photo, that's all that will move). But since it has a metal Shank (plunger knob) I do not know if there is a shank retaining pin. I have repaired a few Onoto's; remove shank pin, replace cork seal, replace plunger washer but with no shank retaining pin how does one disassemble this metal pen?
If any one know's how to disassemble a vintage metal body Onoto plunger pen, please let me know.
