Can anyone help ID this German 1923 note?

Hi, I cant seem to find any information online about this note. Its in great condition, has some back printing and watermark. 

Would love to add it to Numista and log it.

Thank you

100 billion Mark from the city Freital, not yet there as an issuer nor listed in the catalog.

I only found other notes from Freital and one old eBay auction.

Thank you for the advice! I believe the ebay link is from my purchase. Someone from Reddit helped with the Keller reference and I've submitted it to Numista as a new entry N#574817 (pending).

This is the link to the banknote on the Colnect.com website. If you open the link, you will see that, at this time, there are 4 variants. Yours, as link has REIHE G to bottom left. The other 3 are the same except the G.

Still, a great banknote, which I do not have or have never seen
