Old Aerometric Converter Not Fitting Late Targas?

[gammada]

I just gave myself two lovely Targa pens as a birthday gift. One is the Black Laque model, the other is a gold-plated pen with a striped pattern that I've been unable to identify on the sheaffertarga.com site (looks like a Regency sans the black contrasting paint). Both pens came in pretty good condition, with lovely 14k inlaid nibs that were properly treated and taken care of, but unfortunately, both came with cartridge units rather than converters.

 

Upon returning home and doing the cleaning and the flushing, I tried fitting the aerometric converters from both my Blue Ronce Targa and my Triumph 550 (late 70's, early 80's) into the Black Laque pen which I was planning to use on a daily basis on my desk, but much to my surprise, the converters just won't fit! They are lose and don't seat properly on the newer pens. I was able to fit the entire section of the Blue Ronce into the Black Laque, thou.

 

I would have expected these pens to be the same as those previously issued, but this seems not to be the case. Are there special or modern converters for these pens?

 

BTW the writing behind the pens was made with the nib from the older one. It gives a lot of line variation within pretty little pressure. A joy!

Slim Targa pens take a different converter. Are the new pens slimmer than the blue ronce?

Look inside for obstructions.

Hmm it's possible the cartridge piercer has been forced into the section with a non-Sheaffer cart. If you shine a light into the section, do you see a diagonally sliced steel tube?

None of them is a Slim Targa.

Nothing seems to be there. Actually the converter goes all the way down but spins freely and doesn't give any feedback as compared to my Blue Ronce or Triumph pens. There's a little feedback when it seats into the section.

The piercer is right there on these pens, and there seems to be no deformation or obstructions whatsoever. Gonna go to a Pen Shop to see if the modern converter fits any better.

The plastic of the plug in the converter can stretch/become compressed over time so that the converter is a loose fit, and there are slight variations in the diameter of the piercing tube. I've had some success in "resetting" the plastic by immersing just the end of the converter in boiling water for 30-40 seconds, then letting it cool. I haven't had to do it to many, but on the ones on which I have, it's worked.
