Danny it's urban legend (internet story). The story goes as the Russians were pushing the Nazis out of the small country of Belarus. Simonov sent some prototypes to the front and the rifle was a big hit with troops. There are no facts to substantiate the story.

Joe, late last night I came to that conclusion also! I looked at hundreds of photos and articles on the subject but as you say it appears to be just an "internet story". I found nothing.
Cannon I did run across these photos also and wondered IF maybe someone did see an "SKS" during the battle for Berlin in 1945 could either one of these have been the weapon they saw? Of course at the time they would not have known it as a Russian SKS as we know them today.
But one must admit these two carbines are shockingly close in appearance to our favorite carbine. Too close it would seem to me to not be the "father" or forerunner of the SKS!
But, as Joe said..."There are no facts to substantiate the story."
