The Russians bought these revolvers from several sources and didn't request standardization of parts except on "the big pieces". The principle sources were the factory of N.I. Goltyakov in Tula, the Industrialists and weapons makers of Liege and the Emile and Leon Nagant factory, also in Liege. I have never been able to verify that they bought weapons from Galand in Paris (or from the English factory).
The grip plates on your revolver are the same as one previously seen that was attributed to the Romanians. I, personally, don't see enough to connect it.

Both the Goltyakov and the Nagant factory guns are clearly marked and the other Liege contract revolvers seem to have the same grip plates as the Nagant and Goltyakov revolvers.
