Thanks Possum. I just checked again. If they do carry them I can't find them

They do have the standard duofold pressure bars for button fillers. But this one is just a bit different than those. It has an extra piece of metal that clips to the button end of the pen.
Hi There,
I think I know the type you mean, they are a triple type of bar used in the earlier Duofolds, where the bar is not pressing against the section or as in some pens or slotted into the threaded section (Swan twist fillers, differant type of fillling but that's another story). These hook over at the button end, making the pressure bar independant of any stresses on the barrel or section.
The bad news is, that I do think you will only get one other than from a parts pen, and in my limited experiance they are uncommon to come across. I have only handled A/F Victory pens, so can't confirm or deny that, that is the type of pressure bar they used. If you do find a source for them, you could find yourself very popular round here.
Ready to stand corrected on the above.
