Parker Duofolds

[Amos]

I have 2 old Duofolds a Orange one with a single band cap and an a similar aged Lapiz one. The orange writes beautifully however the lapiz is extremely wet causing bleed through. Can anything be done to reduce the flow, I believe it has a christmastree feed.

Have you confirmed there is no damage to the sac that may be causing an air leak?

[Amos]

Yes, the sac has been replace just this week, I thought that would sort it. It is not as bad as it was, but still very wet.

What ink are you using?

[Farmboy]

Is the Lucky Curve intact?

Parker Washable Blue Quink, , band new bottle

[Amos]

No, just asked the repair man, it is a standard button filler, he tells me that the nib should be seated higher, but then could not get it in the barrel. I might cheat and still a modern duofold nib unit in. I have a modern pinstripe that I must have been mad buying

[Farmboy]

A modern Duofold nib unit will not work in an original Duofold.

A picture would help. Sounds like the nib and feed are incorrectly installed.
