Thank you all for the info. I will look here to see if I can find something.
I'm a total neophyte when it comes to Montblanc pens, the only one I know a bit of history of is the 149 which happens to be a pen a friend of mine held dearly. I've always liked the design and the details of this particular pen but I don't know much about the 146. What are the differences between them?
One other question I have is, I've read in many places that the resin that composes the barrel and cap of the MB pens is quite fragile. Can anyone elaborate on this?
As to fragile, don't believe all you read on the internet.
The difference is primarily size. The 149 (piston) is the largest, the 146 (piston)/147 next in size (147 cartridge filled), then the 145 (cartridge) which is still smaller and the 114 (cartridge) the smallest.
