In all the years and many hundreds of Swans that have passed through my hands this is undoubtedly the best one so far! It is a Leverless L205/62 which is Wine And Silver, further described as red, greenish silver and gold. It truly is an outstanding pattern, a wine-dark sea (to quote Homer) of red with islands of silver floating therein and the odd unexpected splash of gold.
There’s not a lot more to say about it. The pen was made in about 1927. It has a number 2 Eternal nib. Other than that, I’ll let the pictures speak for themselves.

Wonderful – and fascinating too.
I have never seen any Swan with a washer clip!

For a time I would have said no such thing existed but then I came across the occasional one. They are not common. I don’t know why but it appears that Mabie Todd turned against the idea.
That is a really lovely pen! Congratulations on the find.
Thank you!
