Found a photo of Romanian Patriotic Guard troops using what appears to be a PM1910 water-cooled Maxim machinegun in the 1970s or '80s. These venerable weapons were used by most Warsaw Pact armies at one time or another and likely would have remained in reserve in significant numbers throughout the Cold War. Its replacement, the SG-43 Goryunov, would be even more common.
Also, this rare bird turned up in Libya in 2016.
