Strong’s This Soviet World (1936) mentions a sort of that internal falsification.

Today the chief fight of the dictatorship [of the proletariat] is against corruption and bureaucracy. The workers, in other words, struggle with their own government, not to overthrow it but to improve it by weeding out inefficiency. A vivid example of this was given by a letter from three railway-workers published in Pravda. They told how the workers of their station, hearing that Sizran station was considered a model, chose three delegates to go and study it. “The election fell on us. However, to our great regret, we convinced ourselves that Sizran is no model.” The letter proceeds to expose fictitious bookkeeping which compelled engineers to list repeated repairs as new in order to protect the reputation of the repair shops, and other false entries which hid inefficiencies. They noted employees who had been demoted for calling too open attention to troubles. They did a thorough and technically accurate job of debunking Sizran, a station on a different railroad to which they had gone in search of good methods. Imagine workers from a station on the Erie giving this attention to study, analyze and reform a station on the Pennsylvania! Imagine their securing ready access to all the records of an alien line! Imagine this as routine news in a metropolitan daily paper, leading to check-up and reprimands of railway superintendents for inaccuracy in reporting their work!
