Help Identify Vintage Fountain Pen

[catalintu]

I just received this beautiful vintage pen I got in an auction and I need your help identifying it.

The clip has the letter P in it and also on the lever. The clip kind of has an arrow shape so I am included towards a Parker but I have never seen this model before. I cheked many of the US brands starting with a P (Packard, Postal, etc.) none has this logo. 

The nib says Durium,14kt Gold plate no 8 USA.A generic nib used by many lessknown brands.  I think maybe is not the original nib since seems a little too big for the feed.

Any ideas? Thanks!!

I don't know what the brand is, but it does have several features of a late 20's or early 30's pen, some pens made at that time were chased black celluloid rather than hard rubber and this may be one. It looks like it is a third tier pen and they were made often with several pen names from the same manufacturer. ("sub brands").  In the 30's quite a few pens look nice, but were more cheaply made due to the depression times.
