HEllo!
I think, you don't understand, how the hallmark system worked in Austria-Hungary. You can see a character in the hallmark. That shows the region. For example if you can see a P, that's for Pest.
My oppinion, the maker is BAchruch Antal in Pest. Check This:

The other mark is not known for me, but we know, that Zipper Antal Henrik (Anton Heinrich Zipper) was the partner of BAvhruch, so it is possible, that ZIPP mark is for him.
I hope, this help.
Best regards!
