The SS runes are constructed using silver bullion over unterlagen, on early quality thin wool, backed with period-style buckram.  So are the rank tabs.  That said, the quality of the embroidery is such that these tabs are definitely post-war made.  The rank tabs are indistinguishable from originals, but were paired with the SS tabs, so are being sold as reproduction as well, though separate them from the post-war SS tabs, and they would be considered original.
