Savoy Pen -- Can't open up the section!

[snedwos]

This afternoon while trying to fix my grandfather's printer I found an interesting little pen called the Savoy. A preliminary google search seems to suggest it's a De la Rue creation.

The pen seems to be in pretty decent condition, the nib is a flexible medium that writes quite nicely when dipped. I really looks like al it needs is a good clean and a new sac.

However, I can't get the pen open. I've tried to apply a bit of heat to soften what I assume to be shellac, but to no avail, and I daren't be more aggressive.

Any pen repair experts who can give me any tips? Grandmia? If all else fails, you'll probably be getting it sent to you eventually.

Done it! It's open, clean and sacless! Now to source supplies.
