Greetings,
I have come across an article with the ownership inscription of R. Shmuel Zev Schlesinger of Ozhgorod, Western Ukraine (previously and historically known as Ungvár).
The only reference I have found of him is a judaic book containing a long inscription/approbation from him that went in auction in Israel some years ago.
I'd be happy to get in touch with his family, if any of you would have any leads?
Thank you
Yosef
