Duofold & Sonnet converters interchangeable?

[otherboss]

Hi all,

 

Thought more experienced heads might be able to help me out. I just bought a Duofold International and it didn't come with a converter. No problem he thinks! I'll just use that extra converter that fits the Sonnet.

 

Well try as I might, the Sonnet converter won't fit the Duofold. Of course I haven't tried the 10 pound mallet yet, but.....

 

Can anyone tell me if there is a reason why the Sonnet Converter won't fit the Duofold, allowing that everything I've heard, says that Parker converters are interchangeable on all modern Parker pens. I've double checked that the Duofold takes the converter from another International and it does.

 

Can the mystery be solved by the great seers of the FPN. That enough sucking up guys?

 

Seriously, thanks for any help you can give me.

Cheers all.

Not enough information by a long shot.

 

 

In what sense will it not fit?

 

Too long?

 

Won't slide into the section?

 

Absolutely positive it is a Parker converter?

 

Posted snapshot might help greatly.

Hi all,

 

Still trying to sort out this convertor problem I'm having.

 

I've measured the 2 convertors I've got and the measurements are indicated on the photo. The only thing I can see is that the Duofold is slightly thicker than the Sonnet and obviously the body section for the ink is also longer.

 

When I put the Sonnet convertor in the Duofold, there is plenty of room between the inside of the Duofold section and the Sonnet convertor, where there is almost none when I put the Duofold convertor in. It is a close fit to the inside diameter. The problem comes when I try to push the Sonnet convertor onto the Duofold post, in the Duofold section. There is a definite apparent difference between the outside diameter of the Duofold post and the inside diamter of the Sonnet convertor, even though they measure the same inside diamter, which is the same as the standard Parker cartidge - 3.3mm.

 

I'm reluctant to force the Sonnet convertor onto the Duofold post and break something.

 

Any ideas, or is there a different convertor for the Duofold International that I don't know about. Everyone just tells me that Parker convertors are Parker convertors and they all should fit in the modern pens. The Duofolds are from the 1990's.

 

I'm crossing fingers here.

are you sure the sonnet isn't a fake one, they are often cloned.

 

hold a magnet near the sonnet nib to check if it is magnetic, if it is, then it is fake.

 

original parker converters should be interchangeable.

maybe you could post a pic of the sonnet and the duofold. it looks like the sonnet converter is too tight.

Are you sure it is a parker converter?

My Duofold Centennial c/c looks identical to the convertor on the right. Its overall length is 72mm, with a maximum diameter just under 7mm. The tip OD is 4.6mm. There are 3 equispaced bumps on it that take the diameter to over 7mm, 15mm from the open end.

 

The pen is a Y.III (Q1, 2007 I think).

 

Regards,

 

Richard.

Thanks for the replies.

 

I have had the Sonnet checked by the Parker distib. in Australia and they say it's an original, so I don't think that's a worry. Maybe it is a fake and Parker here missed it. It obviously has Parker written on it, but that would be normal for a fake anyway.

 

Has anyone got a Parker sonnet converter they can compare (measure)to the one in my photo, or to a genuine replacement? If my sonnet CC is out of wack with the genuine article, then I've got a problem.

 

I'll try to make some time to take some extra photos of the sections.

 

Cheers

OK, here's the low down.

 

The converter on the left is the original style Parker piston converter. I have just plucked a couple of pens from those lying around here, namely a 1987 Duofold and an early Sonnet ('93 ish) and both have this style converter.

 

The converter on the right is the current type of Parker piston converter. It has been slimmed down to fit narrower pens like the Rialto and Vector which were previously only compatible with the slide-action "pump" converter.

 

Both converters should fit both the Duofold (as Richard has confirmed) and the Sonnet. However, I don't have any recent Sonnet models to check this fully.

 

HTH,
