Here's a short story of possible interest. In consolidating my ever-growing collection of pens in various groupings, I ended up with four pens that needed repair work. The group included my MB 149 (deformed section), a Stipula I Castoni Rufino (missing gem on the clip/poor ink feed), a Taccia Staccato Lunar Blue (bad nib) and a Sailor 1911L (broken cap). I decided to send each to their respective factories for the repair work so I could have them for my normal rotation. That was around March 1st. Sent the Stipula back to Italy (via Yafa USA), the Taccia to Itoya Pen Co. (USA), the 149 to their Houston TX repair center and the Sailor back to Japan (via Itoya Pen. Co.). As of today May 24th, I have all the pens back and in perfect working condition. The last two, the Stipula and the Sailor, arrived today.
The Montblanc service center charges a flat $80 fee and thoroughly goes through the pen replacing parts as they deem appropriate (8 days). Taccia replaced the nib for $15 (10 days). The Stipula repair was only $56 including shipping from Italy (44 days). Sailor decided not to charge me for the repair but asked that I pay $20 for express shipping (28 days).
What a deal. I am amazed. Bottom line, IMHO, is there are enterprises out there that still do good, timely and quality service.
Key: Be precise in your description of the problem and be patient.
