Query: SK, but was this a second?

The Sockets each have different levels of impression for the identification. Some were clear and some were lightly stamped. The crows feet were also different physical heights, that meaning as using the five larger and the six smaller units as a gauge, only a couple were the same height laid side to side. I have SK tools, wanted to get USA made tools and sought SK pieces to fill in some gaps, but did not expect to receive this for the price as it seemed like a second run versus a factory run for direct sales.
