Help me ID this Parker Cisele I got from my father

[Kupepe]

Hello,

My father gave me this fouintain pen. It has an 18K gold nib and a narrow hole where the "brush" that sucks the ink from the converter and send it to the nib.

The top and the bottom are flat as you can see. I tried to google it but it does not seem to be a 75 Cisele that had a curved black top. Sorry if I am not familiar with the components terminology ... but I just started with this passion when my father passed his collection to me. Recently bought my first fp, a Rotring 600 fp ... amazing design

Here are the photos.
