Hi everyone...I'm need your collective help (if possible).

 

I recently purchased a beautiful Parker Jack Knife Safety 2 1/2 Button Filler. The exterior of the pen is fantastic and the nib is yummy, but...

 

..I was only allowed to dip the pen for testing at the show, but upon getting it home, the filling system doesn't work. A sac would be helpful, but the metal cage that goes around the sac has become brittle and broken. Is there anyone that works on these and do I need to buy another pen now just as a donor (if I can even find one)? I'm afraid I paid far to much, now that I know this piece is broken. :wallbash:

 

Do you think the seller knew it was bad? What can be done, if anything, to fix my expensive little gem?!

 

All help is appreciated.


So, what's your point? (Mine is a flexible F.)

I don't recall a metal cage around the sac in a button filling pen.  Can you post a picture?

Will have to do tonight. It's on my tablet at home.

 

It's a very odd configuration that I've never seen. 

The metal has become quite brittle and fragile inside, thus the concern I may not be able to fix it.

I think you are talking about the pressure bar that compresses the sac. These are replaceable by any competent repairer.

Idiot I am. It was dim in the kitchen and the sac was stuck to the bar, coming out as one piece!

How Doe the sac/bar/button work with this old feed and can I sac it like normal?

It's quite simple. The button pulls out. Replace the sac as normal and screw the section back into the barrel. Then gently feed the pressure bar down the button hole with the flat plate facing the sac. Finally place the button over the bar end and press home.

 

When operated the pressure bar compresses and bends out while the plate spreads the pressure along the whole sac to improve filling.

Make sure the presser bar is orientated away from the Lucky Curve and put it in last after the section is replaced.
