Sterling silver cameo brooch - Identify the marker and master

[Levon3007]

Hi, there!

This is an antique sterling silver cameo brooch.
There are several markers. But I do not know what it is and in what language. What do you think?
Can you help me identify the marker and master?
Thanks in advance for your help.

Hi,
It is obviously Hebrew lettering. I am sure that a Hebrew speaking member of the forum will tell details.
Regards
