I have it laying somewhere here but you can take Zoli 1900 manual, they have the bolt disassembled and the parts references.
I didn't look for the bolt parts on how they fit when I had a Zoli 1900 in hands, but from visual inspection, apart from the added safety features ont the Zoli (release button) it looked quite identical (but no one really knows before trying).
