Can anyone identify this pen?

[Maja]

I have just seen an Eclipse pen that has the same body shape, art deco cap ring and similar looking celluloid but it is green where this is grey. However the clip is quite different as is the cap top and barrel end. So I am going to search Eclipse pens to see what else I can find.

I have an Eclipse "Vis-O-Ray" model made of the same material (but different cap and barrel styling)

Someone on FPN was trying to ID a pen that was the same as my Vis-O-Ray but in reddish-brown. He did some research and said his was an American-made Swan in red marble & lizardskin, ca. the late 1930's. I couldn't find that pattern in a Swan pen when I used Google, although I know that different pen companies sourced their celluloid material from some common manufacturers....

Whatever it is, it's a very nice-looking pen
