Onoto Delarue Cap

August 14, 2019

Hello,

I have this old fountain pen that I gently restore.

But I do not have the cap

.

Dimensions are near the ringtop : barrel length near 54,8mm but maybe is a short version (52,1 version that has grown

).

Would anyone have an identical one or a link with cap dimensions?

I search the different dimensions to be able to remake one with ebonite.

At first glance, it seems quite simple in appearance.

someone can help me?

Cant help you with the cap but can help with your search.

Your pen appears to be an 'O' model, the shorter model to the 'N'. These later became the 2000 and 3000? models.I believe the cap is common to all these models.

If you search for an Onoto cap using these references it may help.

Good luck.

I have two 'N' models, the pen appears the same as in the Onoto book, 3D pen versus 2D photo make them appear different but they are the same. I am not a pen maker so I hope the photos help.

It's great, I did not hope so much.

A big thank for the time you took to measure these values.

They will allow me to make a preview in 3D that I will show here and that I will test on my version.

Thanks again!

With your help, i create a 3d model oif the cap

Before printing 3d:

And prototype's here

I will use this prototype to turn ebonite blank to recreate it.
