I have owned this particular Waterman's pen for some years, but for the life of me, I've not been able to identify the model.
It has a screw-operated internal plunger for filling, the knurled part that you twist being hidden under a removable cover on the end of the pen.
The text on the pen clearly says "Waterman's" and "60", and "made in England", but I don't think it is like a Ligne 60.
The overall style is reminiscent of a Taperite.
I'd be grateful for any help you can offer in identifying this great little pen.
