I recently picked up an unusual beer stein (tankard?) with a thumb lift I have never run into. It is small, has a marking for 4.5 etched into glass.
Not finding a ton of info about it on the internet, seems scarce.
The glass itself has the crown SG Sächsische Glasfabrik stamp. It has a bubble pattern which I have found examples of but they all have pretty standard lifters. This one has a Prussian Imperial Eagle wearing a crown for a lifter.
Anyone familiar with these? Adding some pics.


I’m not a huge collector so these may be common and I may just be searching incorrectly.
