Helix rod for MB 146/149/22

Manufactured from high density black Delrin plastic, this rod has a circular cross section which is a much stronger alternative to the original oval cross section used by Montblanc

This helix will fit MB 146/149/22 type pens

I also make tools for removing and inserting the 'C' ring, and a new ring is included with each helix ordered.

The link below is a information video of a type 22 pen restoration which is well worth looking at
