Dr Nomis, I don't want to be the bearer of bad news, but I'm pretty sure that right there is a fake.

A few things.

-the pickguard is the wrong shape
-the switch cover is black not cream
-the knobs are wrong
and the big one
-The bridge uses slotted adjustment heads. Gibson NEVER does that.

Apart from the fact that someone was willing to trade a sub $1000 guitar for a guitar worth over $5k.
Please get it checked out and maybe think about getting your strat back.
