Looking For Replacement Piston For Vintage Kaweco Sport 12G / V12

[Papermint]

Hello everyone,

 

I recently found a vintage Kaweco Sport on a flea market. It's a 12G with a gorgeos OM nib. Sadly, the piston mechanism is faulty. I could not manage to get the pen inked and when I unscrewed the piston knob I discovered that the actual piston mandrel (?) is missing. I tried filling in ink after unscrewing the pen and was able to write and enjoy the soft nib but with the thread and seal of the piston missing the pen is leaking terribly.

 

I will attach a photo of the inside of the pen.

 

So I need a replacement "piston part", still not sure what exactly it is called but I have attached a second a photo for you that a nice person in a German Forum made for me to show me what I have to look for. What I need is the little piece "fehlendes Kolbenteil" as pictured! (The picture of the V16 is only to show that I can not use it because it's a different piston mechanism).

 

So, if anyone has this exact part and does not need it in a pen, please DM me! It might be from a Kaweco V12 or 12G, they seem to have an identical piston menchanism.

Oh boy, how could that piece sneak away? I'm afraid that will by very tricky to find. Maybe you can find a V12 in poor condition for parts. But I'd definitely contact H&M Gutberlet to see if they can help you out, they are very kind usually.

 

Good luck

Hi,

I've some problem on my 12G! I need a new cork or seal for the piston of my Kaweco 12G vintage...

 

Have you managed to solve the problem of lack of the piston?

fI doubt that you can find a new cork seal for any vintage pen, just make it yourself it's not that difficult and could be a fun project. Buy a good bottle of red wine, Bordeaux, Rioja, Chianti, to get a good quality cork. Enjoy the wine and use the cork for making a new seal. I bet there are tons of instructions in the repair forum how this is done.

 

And yes, what happened to the stray piston? Any luck finding a replacement?

An o-ring from an Ahab or Konrad will work in place of the cork in a 12: see my post under Repairs from a few days ago.

 

Dang, I have a V16 parts pen. Wish it could work in the OP's pen.

Many thanks for the hint... But I've already contact Tom Westerich in Italy for a new "like original" cork!

 

 

 

But the Ahab o-ring is very usefull for emergency, and the one sell from Goulet is a best buy!
