Where can one obtain spare parts for a Montblanc 146 with a cracked barrel, and is a trade-in possible at a dealer?

Spare parts are available exclusively at Montblanc itself; dealers do not have barrel parts. Repairs take place by sending the writing instrument in to Montblanc, by which the manufacturer prevents counterfeiters from assembling whole writing instruments from individual parts. Before deciding for repair or trade-in, a cost enquiry directly to Montblanc is recommended.
