It's not a 149 or even any swanky limited edition pen but OH MY...I'm in LOVE!!! I have a thing for music nibs and to be able to add this to my collection might be the feather in my cap!!!
Ho Ho Ho!
What's that LOVELY pen that you're showing us?
Is it a Montblanc 246, or is it another model?
If a double-slit, twin breather hole nib isn't swanky enough, I don't know what is.
If it joined your collection, there'd be a feather boa draped around your writing desk.
Wherever you found it, by all means look again. It's a beauty!
Ever since you posted it I've been thinking about it, wondering about it's background.
Many mahalos for letting us see such a marvel.
