Need help to identify this Sheaffer fountain pen.

[Duckman]

Hi, I found a Sheaffer fountain pen in an op shop, can anyone please help to identify what model it is?

The only markings I can see is gold electroplated USA. Thank you.

Thank You.

Closest I've been able to find is a Fashion or Fashion II

Thank you, it came with cartridges in the box, but when I unscrewed it it did not take cartridges, its a type where it has a squeeze mechanism and to shed a bit more light it had a number 10444 on the inside, would this be consistent with the models you quoted? It does not have the word Sheaffer on the nib. 

I have attached another picture.

According to Peyton Pens it's a Model 271 Fashion II.

Thank you all for your answers, much appreciated.

It is a cartridge pen, and the squeeze mechanism is a converter.

The squeeze bladder unit is a removable converter, and as a Fashion II, the pen should accept standard Sheaffer cartridges. I believe the previous generation Fashion used the very rare slim cartridges shared with the Slim Targa.
