Identification of a german (Huettl?) guitar

[rockin_NH]

Hi there,
I found an interesting guitar on a german second-hand trading website, apparently a 60s "Beat star" by the german manufacturer "Huettl".
The problem is that the seller (who is a vintage guitar collector himself) told me that he isn't quite sure about it and also my researches on the internet couldn't find a Beat Star by Huettl (at least it says "Made in Germany West" on the neck plate).
So maybe one of you guys have seen something like that before or could help me to identify this beauty.

Cheers,
Nico

Bridge, pickups and pickup selector look like Framus to me, but don't recognise the model...
