Montblanc 74 And 24 Barrel Swap (Help Needed)

Recommended Posts

Hello guys. I am planning to do a barrel swap on a Montblanc 74 with a Montbanc 24. From what I read, the dimensions are equal and this should be doable. However, I have a few questions.

1: Is the resin used in Meisterstuk line pens different, in particularly cosmetically or durability-wise to that of Montblanc's lower end pens (in this case, a MB 24)?

2: How should I go about removing the piston mechanism? How does it fit and are special tools required?

Thanks,

Eric

Barrel should be the same (same material; only gold plating was advertised in different qualities for different lones) . Filling knob is different.

 

The piston mechanism is friction fit and difficult to remove. You need a special tool or lots if luck, heating and trying.

Can you please specify what kind of special tool I need to remove the filling mechanism and where I purchase one?

Thanks.

There are other ways but those are risky to damage parts.

Ah, I see what that tool is meant to do. I think I don't need the tool. If I damage the barrel in the process, that'd be unfortunate but I have a spare. I'll report back when I receive the 74 in a few weeks.

Yes, if the barrel is cracked it is easy to remove.

 

Good luck

 

Cheers

Unfortunately for me, the barrel is merely scratched- enough to have me remove it but not enough to help me do so. I guess I’ll just have to wait and see.

Thanks,

Eric

Sanding and polishing might be easier.

TTBOMK the diff between 24 and 74 is the gold cap

why not just change caps and swap nibs ???

the filling knob of the 74 should have a little gold ring; the 24 doesn't.

 

thanks

No, the cracks are, or, at least appear to be, quite deep. Sanding and polishing will significantly weaken the barrel, and thin it down by a noticeable degree. Would it be possible, perhaps, to remove the filling knob without removing the entire piston mechanism

Thanks,

Eric

As it turns out, I lost the auction for then broken MB 74. Thanks for the help anyway, it'll help me disassemble the 24 for cleaning if nothing else. Also, how does the first generation MB 121 with the MB 14's nib compare to the MB 14? Or in other words, what are teh differences between the MB 121 and MB 14 besides the nib?
Thanks,

Eric
