Disassembly Of Montblanc Monte Rosa (70S?)

[looookit]

Hello, fpn! I'm new here, so I'm hoping this is in the proper forum etc.

I've recently came across a montblanc monte rosa at a thrift store for close to nothing (~1.50 USD) and I'd like some help with it.

anywhoo, this particular pen won't fill, so I'm guessing there's an issue with the piston. What do I do? The "top" end (opposite from nib/cap) only seems to operate the piston. My feeling is that there's some way to unscrew the feed/nib?

 

Thus far I've soaked and flushed the pen with room temperature water, and tried to gently unscrew the feed, but to no avail. No other monkey business attempted. Any ideas? I'd like to take the pen apart to clean it and assess what's wrong with the piston.

 

I've enclosed one picture of the cap (writing says "montblanc monte rosa"), one of the nib (gold or gold plated, guessing the latter. says "montblanc 2"), and one sort of "top view" showing two notches around the feed and nib.

 

Any help would be greatly appreciated.

Does the knob at the end of the barrel operate at all?

absolutely, I can see the piston moving through the little diamond shaped windows in the body of the pen.

is there no suction at all while the piston is retracted?

 

The nib unit can be unscrewed. but the collar may be tight in the section. soak and then heat while removing, you will have to fashion a tool to engage the slots that you have shown. Personally, I would gently wiggle the nib out and then pull the feed out instead of attempting to unscrew the collar.

 

Once the nib and feed are out of the way, you can check for suction and see what's wrong with the piston seal and maybe see if a light coat of silicone grease improves things. If the elastomer seal is shot, finding a replacement might be a problem, so you may have to fashion something out of available stuff.

Every time I see a Monte Rosa come up on these boards, it's a different model! I have a Monte Rosa that looks a little like yours, with a metal cap, diamond ink-view windows, and an exposed nib - but I've seen later models with a hooded nib. AFAIK they all have gold nibs, even though the Monte Rosa was on the "student" end of the MB line-up.

 

The nib and feed unit on mine unscrews (and unlike most MontBlanc nib/feed units these days, it does so without the need for a MB-specific tool) with hand pressure, like an Esterbrook renew-point; unlike a renew-point, I can then remove the nib & feed from the collar.

 

 

That "top view" looks pretty gunked up. Give it an overnight soak in water, then some dilute ammonia, maybe also soapy water. Once you've soaked and cleaned, be gentle; I can only say what's true for my Monte Rosa, which is that it unscrews by hand without needing a tool, and can't guarantee that's the case with yours.

The Monte Rosa was a separate line, with many models to choose from. The Stefan Wallrafen Book covers this line well. Many had GP steel nibs and a few had solid gold nibs as well.

I - and my lack of book learnin' - stand corrected. Are the 14c nibs always marked as such?

with Mb? yes, 100% of the time.
