The Parker Premiere/Duette Sr.

This is a depression era Parker Premeire (also known as the Parker Duette Sr. in the USA), manufactured in Canada sometime between 1932 and 1934. 

I believe these models were known as 'Thriftime' pens, coming after the great crash in 1929, when their flagship pens cost a lot. To save on manufacturing costs, Parker started manufacturing cheaper 'school pens'. 

The Premiere/Duette Sr. has a flat, clip screw of the same material as the pen body and a Duofold style ball ended clip. It sports a single, narrow, gold filled cap band, a black section, a blind cap in the colour of the pen and was a button filler.

This particular colour is called Red Onyx, I think. The 14k Canadian nib has a little bit of flex and writes medium to broad, and very smooth.
