Is this a cheap fake

[Janecre]

Hi
I have been told my pen is a 1980s rep pen from a conference but it is nothing like any of the ones on here. It seems light and cheap. No serial number and nothing saying made in Germany. On the pen barrel the white star isn’t in resin it is just stuck on and on the lid it is flat. Please can anyone identify it for me. The nib is totally different too

Many thanks
