Other than in the Russian archives, I don't know. However, I think you already know of some of the other "State Committees" besides the poster boy Gosplan (Gossnab for Material-Technical Supply, Goskomtsen for Prices), so look for more out of those non-Gosplan organizations.

"A new centrist project does not have to repeat these mistakes. Nobody in this topic is advocating a carbon copy of the Second International (which again was only partly centrist)." (Tjis, class-struggle anarchist)
"A centrist strategy is based on patience, and building a movement or party or party-movement through deploying various instruments, which I think should include: workplace organising, housing struggles [...] and social services [...] and a range of other activities such as sports and culture. These are recruitment and retention tools that allow for a platform for political education." (Tim Cornelis, left-communist)
