Update:

Thanks to Leigh Reyes and David Nishimura, I have the following information;

“English Syringe-filler with a cap from a Japanese pen. First decade or two 20th century. Made for retail by W H Smith”

–

Alright folks, before we get into this weird pen I received in the mail today, I would like to preface this post with an apology for the aesthetic presentation of these photographs. Artificial lighting + needing to have the images as clear as possible for identification means colours & tints are not accurate and generally bleh.

Now that this is out of the way- the pen in question has the following markings-

The “Jap” No.2 & Made in Japan- marking is super clear and deep as you can see.

On the nib we have some kind of logo which I can’t make out or recognise as well as the 14CT mark which is unremarkable.

As you can tell, flex is decent.

The cap fits on and is held through friction fit alone. No threading.

Filling mechanism is a plunger style, cork needs to be replaced but otherwise condition is very nice.

On the body, Self Filling Pen – Patented.

And that logo once again.

A few nice details on the end of the body.

And finally for size comparison. It ain’t particularly short.

To me it feels older that the 1950’s based on style but the branding makes me think this was manufactured in Japan to sell to the U.S market so I am quite befuddled. I have found no traces of this pen online so if you have any thoughts- this is an official help me please request!

Thank you thank you.
