This was single model for all Red Army military personal who was entitled to wear the saber (primarily cavalry and horse drown artillery, but not only them). Here are variations of this saber and to the left is dragoon’s saber model 1881/1909 that was manufactured by soviet’s up until 1928 when production was completely switched to model 1927, but it was in use in WWII .
