i dont quite agree, its the same with the knights cross, you can easily tell postwar and pre-45 Knights crosses from their die flaws. The same is true to the EK`s, even in the period they had die flaws, which later become even worse, which is quite obvious why., like on the S&L post 45 KC-`s, plus as mentioned the Rudolf Souval company made awards, well on the EK1, its also easy to tell which is post and pre 45, the hardware is not the same.
