The DP28 or Degtyaryova Pekhotny "Degtyaryov's infantry machine gun" introduced in 1928 (hence DP28 code, the Russians had a very simple and logical method of creating their equipment codes). The pan magazine could hold 47 rounds firing at a rate of approx. 500rpm.
This effective weapon saw service throughout the WWII by both the Soviet forces and the Finnish army, which captured thousands during the Winter and Continuation Wars, and was later used in large numbers by Communist forces in Asia.
These figures are from the 28mm plastic 'Russian Infantry in Summer Uniform' set.
The tree stump with roots was made using the same method described in a previous post (click here). It adds a little detail to what would otherwise be a relatively bland base.
