I've had this elegant Waterman pen for at least the last six years. It worked fine when I received it, but I have recently had to replace the sac. As you can see from the writing sample, the pen is working perfectly again.
I have no idea of the model. This didn't bother me when I got it, but it does now.
I've been unable to find any clues online. A look at the family photo on the Raven's March Fountain Pens website tells me that it might have been inspired by the Citation and Conquest models, and it looks very 'space age' to me (could fit into the Atomium in Brussels). So I'd guess it is a 1950s pen. But I'm an ignoramus when it comes to Waterman pens, and even that could be wrong.
I'm pretty sure it's made of plastic. The ring, clip and lever are silver-coloured. The nib is marked "Waterman's" and "18Cts". There is also what looks like the top half of a "7" at the back of the nib where it disappears into the section. The barrel is marked "Waterman's" and "Made in France" across two lines. This is just about visible, but I was unable to take a photo of the barrel markings.
Guidance gladly given gratefully received! Here are some photos (apologies for the poor quality).
