This is a topic that we may never know the real reason why this marking was applied. During the early years, prior to serious internet use, some G43 book authors
did not seem to accept that these markings were original WWII..hence it is not really mentioned in books. It was known by serious g43 collectors that these markings were of WWII origin, and only on certain late BLM QVE made sniper rifles.
They appear random, in certain late letter blocks, but not all of those matching sniper rifles received the marking it seems.
Nobody will probably ever know for sure and I'm sure all the factory records have been lost to time in some storage Russian facility.
What seems to be an accepted "opinion" is that BLM was having difficulties getting supplies of ZF4 scopes and/or mounts at the time. So, in the meantime, while waiting for the mounts/scopes etc. to arrive, they decided to mark the rifles that passed the "accuracy/Sniper" requirements with the ZF K43 marking. Therefore, when the needed items arrived, they could apply the scopes to them? Just an opinion here. The point is, they randomly show up during late QVE production.
From a collectors standpoint, having that marking on there would verify that the specific rifle was intended to be a sniper.
