I bought Duro Yellow Tiffany LE from an individual recently.
(casein barrel black cap and section)
However, I do not understand whether that the pen is converter or button filler.
For an amount-limited model, I was not able to search even Web.
Please teach me it who has the same pen.

Greetings Friend,

Congratulations on your purchase of the Tiffany Duro LE in yellow. It must be a beautiful pen. Maybe you might consider posting a picture of it here so that we can all see how nice a pen you've purchased.

If your pen is a cartridge/converter filled pen, the body of the pen will screw off at the nib section. Inside the pen will be a converter, which looks like a clear tube with a screw-down/up piston that creates a vaccum-like pressure differential. This draws ink up through the nib assembly or expells it depending on which direction one turns the converter piston.

A button filler model would be one on which the end piece on the body of the pen screws off to reveal a button. One pushes this button, which in turn puts pressure on a pressure bar, which presses up against an ink sac. When one releases the button, one releases pressure on the ink sac, which in turn draws ink up through the nib assembly into the ink sac.

I hope that answers your question. Happy writing.

Peace,

Phroneo

T.I., is your pen similar to the one on the far right? If yes, my Duro is a c/c filler. Great writing pen in a nice medium nib (loaded with FPN's Manuscript Brown ink).

Thank you Phroneo, Paul.

My tiffany pen was firm and did not screw off yesterday.
When I thought about the rarity of this pen, I was not able to leave it to power.
I tried again today based on two advice.
The result ... I succeeded screw off.
It is my first Conway Stewart pen, so I do not understand this pen.
I use it habitually for a long time from now on.

Well Guys,

You both have beautiful pens.

Nice collection of CS fountain pens, Paul. How I wish they still made the resin Duro (or the the Nelson in more colors) because I miss that pen.

T.I., Thank you for posting a picture of your pen. I think that you'll find it to be a wonderfull writer - smooth and reliable - particularly with that converter.

Don't forget to clean that entire nib-feed-converter assembly out every three or four charges of ink by using tepid - room temperature - water. Just keep on bringing water into the pen until it comes out clear and the let it dry before you put new ink into it. This will assure that your pen will give you years of trouble free service.

Peace,

Phroneo

PaulK, what are the colors of your leftmost and rightmost Dandy? I have the Azure, so I recognize that one.

I'm working on a laptop right now and it is 11:51 pm in the UK. Please forgive me if I incorrectly recognise the materials because it has been a very long day in the office and my eyes are tired.
