Hello!
The second sets of marks are tax marks from Austria/Hungary.

The first mark (IH) is the maker's mark.
I think, the 2. mark is upside down. Maybe 2 crossed sword. I guess, it's german, one of the cities with similar guild marks. (Dresden, Weissenfells) Maybe some of the german contributors can help,
Best regards!
