Both 146 and 149 can't use one so they can't be it. However it looks like a Meisterstuck 144 (classicue) or 145 (chopin) since you mention the cartrige/ converter. Looking at the picture, I can't really say if its gold or platina. It can use a cartrige or its mb converter.

The nib's engraving says 4810, 14k and some other small 3 digit number starting with 5. To help you with your pen, maybe you can post a picture of it? Or tell more about the model (color, material, nibcolor, filling system ect.) There was a website with all the montblanc models but I cant find it back right now. Pix isn't a linieage of the meisterstücks for what I know. I have a Mont Blanc Meisterstuck Pix and I am trying to find out how and where it fits into the Mont Blanc linieage of fountain pens.
