Austro-Hungarian antique mark, which maker?

[13lat]

Hi, I'd like to ask for your help, again :)
I have a tea service with these marks, can you recognize them?

1836, Vienna, "AZ" maker's mark
There are another sign at the bottom of each piece: "Walln.." or something like that.

Thanks for your help!

Hello!
AZ is Alois Zitterhofer's mark.
The other mark belong to a totally different maker, Karl Wallnöfer.
Best regards!
