herring safe details welcome !

[stephane]

Hi guys. hard time with the pandemic to find safes too but unexpected discover next to switzerland in french alps. from a 2 generation dutch family. i suspect this safe had made a complete planet tour before falling in a cottage in the alps !
i found photos on the web of "herring & co safe" and "herring hall marvin" so wondering if there is a link between this 2 manufacturers ? i saw a number behind the handle but forgot to write. can remove and post if help.
i don't know what's meaning "sole agents" under names on the door. unfortunately no originals wheels but i have cast iron just need to check if i can install.
i will be happy with details and periode of manufacture.
merci beaucoup
