These shells fit all Parker Classic and Parker 180 fountain pens
The plastic on the shell casing has a tendency to split after a while. You can transfer your old nib onto the new shell
There are several other Parker models which have shells which look similar to the the Classic/180 but take slightly different shells. So you can check whether this is the shell you need, check these measurements: this shell is 44mm long and the diameter of the thread connector unit is 7.5mm
If you are still in any doubt, please email us a picture of your pen showing cap, barrel and nib unit
