I recently acquired a Parker 21 that is missing its sac. The metal aerometric shell is in place, just no sac. I would like to replace it myself but can't find any info here or on YouTube about putting in a replacement sac for a Parker 21.

 

My experience level-I have extensive knowledge of 45s but little on older pens with sacs. I have replaced the cracked hood on another 21 I bought. I have watched Danny Fudge replace several sacs on Esterbrook Js.

 

My questions:

1) Are there any videos or guides for replacing the sac on a Parker 21?

2) Will I need to remove the hood to remove the aerometric filler?

3) Do 21s have a breather tube? (I don't see one on mine)

 

Thanks for any suggestions and advice.

Replacing the sac on a 21 is the same as replacing the sac on a 51. You have to pull the sac guard off to get to the sac. The originals were PVC. David Nishimura's 51 sacs are PVC, and should fit the 21.

 

The 21 typically has a short(er) plastic breather tube, not the long metal one of the 51 aerometric.

Thanks Ron.

Will I be able to remove the sac guard without removing the hood?

Is the breather tube essential? If so, any suggestions on finding one?

 

Thanks again,

Cabbie

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.

      I suppose the update issue could be mitigated.  One would post a link in signature, to the particular part of your profile where you list the inks that you're willing to post samples to others, gratis.  But looking at profiles, I suspect that would require an edit to the board's software, potentially a nontrivial task.

      I read your idea as getting willing givers to publicly register as members of a set of heterogenous servers, in a system in which a client would explicitly select an available server from a list, to which he/she will then send a request privately and asynchronously. Request handling in the system is unmanaged, and individual requests are handled by the targeted servers completely independently on each other. I think the model is fine, although there are some operational concerns you may want to
    • Daneaxe
      First thought on the method/system of ink sharing: Think the best way, to begin with, is to follow the way of the US thread: offer up a (small) list of inks you are willing to PIF, to whoever expresses interest. Write clearly in the "mission statement" how it works, with a tiny "quid pro quo" that even a struggling student can comply with, i.e. post your opinion and a writing sample, with option of a full review if desired.   So yours truly might say: "I'm offering up samples of D
