Helix rod for MB 146/149
MB compatible Helix Rod
Manufactured from black Delrin plastic, this rod has a circular cross section which has the merit of being a much stronger alternative to the injection moulded version which had a reduced oval cross section
It uses the same end design and is fully compatible with both the 146 and 149 pens.
Of course in order to complete a repair, a serviceable 'C' washer is a must. These are now available in packs of 5 on this site.
As with all pen repairs some knowledge of fitting spare parts is desirable.
Please follow the links below for a comprehensive description of this part from a renowned repairer of M.B pens. I think they are quite interesting.
