How do you get spare parts for a Montblanc 220 (especially the star inlay on the barrel end), does a modern converter fit, and does the model have collector value?

A single star inlay is practically not obtainable as a spare part; a restorer would have to scavenge a complete 220, which is uneconomical. Montblanc discontinues spare-parts supply for non-Meisterstück models 10 years after end of production and destroys the remainders, so sending in only costs postage. On the converter question: there is no prescribed standard converter — best try various piston converters at the dealer; one fits in experience. The black 220s have, due to lack of rarity, no collector value at present; they remain, however, good use pieces, qualitatively under pre-war and new productions.
