Just found some interesting info regarding Klira.
Apparently Klira manufactured guitars under other brand badges as well as their own, namely Triumphator and Holiday. They also distributed some models via a German electronics catalogue in the 60's called Quelle. These catalogue models were unbranded and produced as white label products, i guess so the catalogue could claim them as their own?
Could well be the reason for the lack of branding on this model and may well have been manufactured specifically for that catalogue??
There's a "Lady" in this thread with identical features but a different headstock, apparently branded Triumphator:

So it is clearly a Klira or a close relation of.
If anyone has more info regarding any of this i would love to hear it!
thanks
