How do I refill a Vintage Conklin no. 256?

[Kaivyn]

I just got this pocket pen and I can't figure out how to refill it. I got it from my grandma, who hasn't used the pen in years and also doesn't know how to refill it.

 

The grip and barrel look like one solid piece of plastic  (with the exception of the medal thermometer-shaped clip(?) on the body). 

The barrel reads: 

 _NO.                 Conklin                      _TOLEDO

²⁵⁶        RE G.U.S. PAT.OFFICE           ^OHIO

_{(The "R" in RE might be  a "P" - there's a crack there so it's hard to tell.)}

 

The pen has a heart shaped breather hole. The nib says "CONKLIN" over a large  "2"

Where the nib meets the grip section, I can also see the top half of 5 letters - it looks like it says "OLEDO" or "OLFDO." I'd have to remove the nib unit to be sure, but I'd prefer not to mess with the alignment of the nib unit if possible... but I'm not confident that there's a way to refill this pen that isn't removing the nib unit. 

 

I can't find a Conklin 256 on Conklinpens.com, and other google search results aren't helping either.

Any ideas on how I  could refill this pen or where I could learn more about it would be much appreciated!!

That thing you call a clip looks like a lever to me. Does it move at all? If it's been unused, the lever might not even move... but if it does, and the sac inside is intact, moving it out, putting the nib in the ink, and pressing the lever back to its normal closed position, should fill it with ink. (It worked with an old old Morrison Tourist that I got). Maybe google Conklin lever filler....

Good luck!

The "clip" is a long style lever.  Slip a fingernail under the large, round end and gently pull it up until it is perpendicular to the barrel.  Dip the nib and part of the black rubber next to the nib in the ink and push the lever back to it's original position.  Remove the nib from the ink and wipe off the excess ink with an absorbent cloth. 

These long levers are fragile which is one reason they were replaced with the shorter version after limited production.  If the lever doesn't move fairly easily don't force it.  The rubber sac inside the barrel may have hardened and will need to be replaced.  Forcing the lever could break or bend it.  If you can get to a San Francisco Pen Posse meeting I'm sure somebody there can evaluate it for you.  The resac job, if necessary, is easy.  Maybe @FarmBoywill jump in with meeting info.

 

It's a nice pen that has been around since Warren Harding was president.
