Could you help identify this pen?

[JamesEdward]

Dear readers, 

I was hoping you could help identify this pen. Searching for "Swan piston filler" and derivatives thereof have not yielded any helpful information.

I'm looking to disassemble and restore this pen, as it is leaky from both ends. 

 

Many thanks for any help you can offer.

 

If pictures are of too low a quality, I can provide better ones.

What dies it say on the barrel in photo #1?  We need to see the clip, please.

[JamesEdward]

It says "Swan" | "Reg. Trade Mark" on two lines.

Update: While taking the photos and tinkering, the piston unit has come out, as have nib and feed. The blind cap is stuck to the piston unit now (wasn't before) so that bit is going for a soak as we speak.

Have a look at the following post: cap and barrel kind of have the same shape (except for being a button filler and open nib:( )

Thanks! I'll include some more pictures to potentially get more of an idea of the setup.

The Stephen Hull book page324 shows this pen as a very late production 1960s Swan.

Hurrah! Many many thanks! The rubber on the piston of mine is worn (brittle and disintegrating) so that'll need replacing. The rest of the pen is as in the picture in the book. Thanks a million for your help!

That is what makes it so much fun to post here!

Do you think it would be of interest to anyone? It came to me in a package deal with other pens. I like it, it super fine and very responsive, but it won't be a daily writer for me. Also, not much of a Swan collector. Yet, that is. Haha.
