Unknown maker

[Zolotnik]

Hi all -
got this Niello page turner assayed in St. Petersburg, made by НП. In my sources I can not find a fitting silversmith.
Qrt.S provided some names but no marks:
Nikolai Paldani
Nikolai Pestjakov
Nikolai Podgorski
Nikola Petrokov
Who is it?
Any help very welcome!





Regards
Zolotnik
