Calling all stein experts #2

Got this 0.4L glass stein recently and can’t ID the maker or date it. The mark inside the lid is either “AW” or “WA”inside a stein and there is a German word indicating design protected etc. Tried searching stein.org but no luck. Might have missed it. It could have a little age to it as the glass base is quite uneven and a little rough on the bottom. Can anyone tell me who the maker is?

Data

20cm High, 8.8cm round, 0.77Kg

Cheers

 

You can't trust what you read in a listing, but I thought you might like to see another one, different lid: https://www.worthpoint.com/worthopedia/antique-german-mold-blown-glass-beer-2064958868

 

Nice catch. I've seen this vertical glass ribbing on other Victorian era glassware as well.
