This is a third-tier fountain pen made by Ambassador.
I find its celluloid attractive.
It is a lever filler with a new sac installed.
It comes with a 14k nib which writes with a medium point. Semiflex.
Gold-filled trim shows wear on the clip and lever more so than the wide cap band.
A transparent feed.
Not personalized. 
There is some warping of the celluloid where the lever sits and toward the barrel's end. This is more noticeable finger over it when you run yo.
About 5" long.
I will make a nice intro to the world of vintage fountain pens.
