Pen experts - please help me with this. These photos are from a friend of mine. It seems to be a very unusual Sheaffer converter. The following narrative is from my friend describing his experience with this converter.

" There is a hole on the end so it fits in the pen just like a cartridge. I think I might have figured out how to fill it, but if you can get any info on it I'd appreciate it. There are two pictures of it, one with the plunger out, one with it in ... and a regular Sheaffer cartridge in the picture for size comparison.

Mike Carter thought it should fill on the down-stroke of the plunger, but it doesn't, so it's not like a Touchdown filler.

It does fill (a little) on the up-stroke of the plunger, but then if you remove it from the liquid and push the plunger in, the liquid comes back out.

I think I got it to "fill" by placing the end in the liquid, pumping the plunger back and forth about 5 or 6 times and then removing it from the liquid after the last down-stroke. It doesn't seem to hold much, only a few drops. Anything you can find out would be great ... operation, age, rarity. "

Anyone have some insight on this converter?

Thanks!

Hi,

Here's a thread discussing this converter.

Actually, it works very much like a Touchdown filler, filling on the downstroke...if it's working, that is. Many surviving examples are no longer in working condition.

Cheers,

Jon
