It is not an Ahab or a Twsbi. Don't go yanking it apart...it's not made to do that...and they get ruined sooner or later...bet on sooner.
Piston pens are not made to be taken apart unless it is a 800/1000....and then seldom to never.
You need some 100% pure silicon grease. Buy the smallest container you can find. It will last you a life time. Half a rice corn on a toothpick smeared around the top of the barrel under the piston....is all you need every year or two.....You can smear that small amount on a Q-tip too.
Rick Propas the Pelikan Guru says once every three years...does well enough.
But if you are changing inks 3 times a week or two...the pen can get stressed from the constant working the piston to get old ink out...can get dried out too. ... no problem.
Tricks....so you don't work the piston a lot...drying out the insides. Get two rubber baby ear syringes, one leave regular. Unscrew the nib, squirt the insides of the barrel clean. You can use this to clean out all your C/C pens too.
The second...cut it so the inside of the nib shaft fits inside....then just squeeze the water through the shaft and nib.....your nib and feed is cleaned of other inks in a jiffy.
If you do both...should not take you more than 3 minutes total time from the time you twist the nib out to when you twist it in to have cleaned your pen.
To be 100% shake the pen in a paper towel like an old thermometer and let sit in a cup wrapped in the paper towel for as many hours as you feel....4-5 or over night depending on how 'clean' you want the nib to be.
Do put some money away.....50 years from now you may need a new gasket.
Stay away from Red inks.
Purples should only stay in the pen for a week or two....they do also have a rep for staining. One can live with out red.
If you get a needle syringe....flatten the tip. Go to the drug store, with your sharping stone, tell the person behind the counter you want the widest needle and 10 or so ml syringe to fill your ink cartridges with. If you take off the edge, before their eyes...you should have no problem buying one in the States. I live in Germany so things are different.
You can fill your cartridge with great looking purple inks with no fears.
