I have the Bach special edition Montblanc and its piston is tight. The twist does not turn smoothly. I called Montblanc Boston and the rep had no idea whatsoever as the cost of repair. She told me it would take about 6 weeks to repair and that they send it to Dallas TX. I am thinking of sending to Bromfield Pen in Boston. Any idea what is should cost? $40? The Bromfield website said most of their repairs cost $40.
Is the repair easy to fix yourself?
