MV Adaptor – How to use
Here is a step by step of how to use the Esterbrook MV-Adaptor.
When you buy an Esterbrook Estie it comes with a #6 JoWo nib in EF, F, M or B. We
have engineered a 2nd grip section that will fir the Estie and a vintage Esterbrook
You first need to remove the barrel of the pen from the grip section as you will
putting on the MV-Adaptor in its place. When using the new MV-Adaptor grip
section you will want to use the 2nd convertor provided for a secure seal. Put the
MV-Adaptor section on the barrel as this will give you a better grip when putting
the vintage Esterbrook nib unit into the MV Adaptor. To insert the vintage nib you
will hold the top and bottom of the base of the nib as show. Then line up the base
of the nib unit to the MV Adaptor section and screw it in turning clockwise. Be sure
you are lining up the threads so you donʼt cross over them. The vintage units are
all very old so understand some will be much tighter and take a bit of force turning
to get in. This is where applying a tiny amount of silicone will help. The threads on
the MV Adaptor are much stronger than the vintage Esterbrook nib unit so it will
hold true to form while you turn in the unit.
Once the vintage unit is seated fully as show in the pic you can not unscrew the
section with the nib unit seated and fill it like any other converter filling fountain
The cap of the pen has what we call a cushion closure cap that seals in the nib
from the base of the section. On the JoWo nib units it is not that necessary but on
the smaller and generally much finer as well as very old vintage Esterbrook unit it
really makes the difference. Now when you pick the pen up a few days later
without use it will be wet and ready to write every time. No more hard starts due to
the nib drying out.
