Assistance Required in Identifying a Waterman Fountain Pen Model

[jorgepenalver]

Hello.

Attached to this post is a photograph of the Waterman pen in question. I have observed some features but am unable to pinpoint the exact model.

I would greatly appreciate any assistance or guidance you can provide in this matter. If additional photographs or information are needed, please do not hesitate to let me know, and I will provide them at the earliest.

Thank you in advance for your time and help.

Warm regards,
