Difficulty with old Austro-Hungarian hallmarks

Hi, I was recently looking at some old Austro-Hungarian cutlery, and managed to identify one set as Joseph Carl Klinkosch, but I cannot identify the other sets. Would be thankful if anyone could take a look.

The last image looks like the import mark used between 1902-1918. The small A in the left side of the mark identifies Vienna as the town.
