Are these Georg Roth marks?

[AllSeasons]

Hi, I need the forum's expert help in identifying/confirming these marks. My initial guess is that they are Georg Roth, but wanted to really confirm, as this is a pricey set. There are 4 items in this set in total, so I'm posting 4 (similar) marks, one mark for each item in the set. Hopefully this is okay with mods. Thank you very much in advance!
