SW only numbered the right grip. So, that part is correct.

I'll play the other side here regarding the box. We don't know that the seller was the one who altered the number on the box. He might have bought it that way. A high volume seller might possibly not have noticed. In my opinion you got a nice gun at a GB price and a worthless old blue box. Ask for the price of the box as a refund and go shooting.
