Hello there,

Iím very lucky to own two Montblanc 146s, one from the 1980s with a plastic piston, and one made later with a brass piston. The plastic piston pen is my very favorite pen and is perfectly balanced in my hands. The one with the brass piston feels a little too back-weighted to me, similar to the Pilot Custom 823.

Is it possible to replace the brass piston for a plastic one? If so, does anyone know any repair people in the U.S. who would be able to make that swap?
