Seeking Repair Advice For A Scholar Piston Filler

[hardyoyo]

I picked up a sweet little German piston filler on eBay, I think the manufacturer is Scholar, though the pen is inscribed "Student" It looks a bit like a Pelikan 200. Has a blind cap. I don't think it is "clutchless" so I am at a loss for how to remove the piston rod. The seals need to either be replaced or greased. Any tips for how to take this pen apart! Thanks!

Turns out patience and persistence were all that was required, I soaked the pen, and then discovered that the section slides out from the barrel, the whole ink window is part of the section. Now I need to replace the gasket/cork, I am thinking o-rings. And that section needs some sort of sealant, I am thinking Shellac would do, but there is probably a better alternative. I will see if I can figure that out.

Hmm... looks like I may want to consider a purchase of rosin-based thread sealant, though this discussion

has me thinking that shellac might be OK for my application, since this section isn't threaded at all, and shellac will make a water-tight bond, which can still be released with heat.
