Sheaffer Crest Nova cap - Disassembly and cleaning inner cap?

[Medieval78]

Hello guys

 

I'm looking for advice how to remove an inner cap from a Sheaffer Crest Nova (1996-98) cap? The previous owner left the pen with installed cartridge for long time and some ink messed up inside the cap. I think some ink have still been trapped between inner element and metal cap. Do you know if this cap can me disassembled safely without special tools? That inner cap looks like a plastic tube installed inside the cap. I attached photos for reference.

You indeed need a special tool to remove an inner cap, see here: https://goodwriterspens.com/2010/12/13/tools-the-inner-cap-puller/ or here:

The inner cap usually needs to be removed to access the inner connections of the clip or a cap jewel, not really for just a cap cleaning. Rinsing extensively with a mixture of water with a bit of ammonia should suffice.

Thank for that. I'm wondering if those tools were designed for vintage Sheaffer Crest model only  or both (original and modern) as my one is the modern re-edition from 90's.
