Help Identifying Vintage Montblanc?

[Cluelessasian101]

Hi everyone, I was lucky enough to attend the Fountain Pen Shop's final sale where I picked up this vintage Montblanc.

I was wondering if anyone had any clue about it? It has a gold nib that flexes and is labelled Montblanc, 14C, 595. It appears to be a push button vac filler. I couldnt find much online, so if anyone would be kind enough to share anything about it, I'd be very thankful!

Difficult.

Could be a 333 from the 40s.

It doesn’t seem to have an ink window, and you said it’s a button filler, so I might be a 324. But the blind cap at the bottom should have a number imprint and the barrel too should have an imprint. The section doesn’t look like a period appropriate fit to me though, and the blind cap seems to not be perfectly streamlined with the barrel so I wonder if these parts are replacements. If it is a 324 then the nib you have is from a later time too. These are just random guesses though. The pen looks lovely and the long tines on the nib look like they are meant to flex. Enjoy the lovely pen
