So I won this pen in an auction (yeah already sounding like bad news) and while it seems like the other pen that I got was real (I think maybe a 144? is a cartridge pen) this one seems like a fake to me. The serial number looks to have the wrong font, although when I looked it up no other listings for a pen came up. Also, the imprinting for the nib seems too shallow, and the piston is very stiff to turn. I did put the nib to a magnet to see if it was steel but there was no response. But this is my first experience with any type of Montblanc, fake or real so I'd like a second opinion before I just sell it (ofc stating that its a fake in the listing). Thanks for your help!
