I am looking for a paper titled The Cauchy integral by M. Privalov (Saratov, 1919).

The paper is written in Russian. It is being cited (for instance) by A. Kolmogorov in the paper Sur les fonctions harmoniques conjuguées et les séries de Fourier (Fundamentals Math. 7, pp. 23-28 (1925)), which is written in French. Kolmogorov cites it as 'M. Privaloff - L'intégral de Cauchy, Saratoff (1919)'.

Unfortunately, I don't know much Russian, so it is not possible for me to use any Russian website where Privalov's paper might be available. I have been searching for it, but apart from other citations there seems to be no information as to how one could access it via internet.

Does Saratov even mean an actual journal here, or is it just the author being a member of the Saratov State University?

I'd appreciate if someone could give me a hint. Thanks in advance and apologies for the possibly naive question!
