Esterbrook cartridges

[etohmartini]

So I picked up a CX-100 that seemed to be retrofitted with an aerometric filler unit that isn't right. It sits on the nipple, but the diameter of the filler body is just a shade too large. Unscrew the section and the filler remains in the barrel. A gentle rap on a hard surface will dislodge it, but then ink spurts out and that's not going to fly with me.

 

Lo and behold, my local antique shop had a box of 4 Esterbrook cartridges (the shop owner politely rolled his eyes at my joke: "but it says '6 for 49¢' right on the box!"). To be frank, I think I underpaid. A lot.

I popped the seal of a cartridge and the ink was still wet. A little gummy, but wet. I syringed it all out, let it dry, and filled it with some Sailor Blue. The pen fed instantly and I am a happy camper!
 

While it does not have the spacers that were originally in the box, the fit of the cartridge to the nipple is very tight. I might create a spacer if it becomes necessary.

Nice! They show up on ebay occasionally, but it's more fun spotting them in the wild. I've found them in "junk" bins at flea markets.

I have adapted Sheaffer cartridges for Esterbrook pens, in the CA-101 models primarily.  I cut a spacer from a long Berol eraser that I can get locally, then put a 1/8" pilot hole in the Sheaffer cartridge.  I need to see if the CX-100 barrel is wide enough to fit the Sheaffer cartridges.  Old Sheaffer cartridges were designed to fit old Venus pens, so I think it should work.

I have been able to get a Platinum converter to work on a CX-100.  Just needed to add a ~100 microns to the diameter of the feed nipple in the pen (by adding three coats of pen shellac and letting dry).

And....the barrel of the CX-100 is just barely too narrow for a Sheaffer cartridge.
