• This connector is manufactured in black acetal.

The thread is 36TPI which calculates at 0.7mm pitch.

It will fit the nibs on the feeds on the following models from the 50's to 70's

Pelikan 120 type 1 (Type 2 uses the 1970's Merz & Krell Type collar)

Pelikan 140 all models

Pelikan 500 and all variations 500N 500NN

Pelikan 520 and all variations 520N 520NN

Pelikan 600 and all variations 600N 600NN

If  the collar is a fairly tight fit I recommend to apply a little heat in order to expand the bore slightly.
