My understanding is that from the late 1960s, the USSR became the primary supplier of small arms to PAVN/VC/communist forces, by a 3:1 ratio over PRC. However, my (admittedly limited) reference sources w/photos of the SKS in Việt Nam depict only Chinese-made (Type 56) rifles.
Does anyone here have digital photographs of Soviet-made SKS rifles in Việt Nam they would be willing to share?
My thanks in advance, if so ...
