sure you will sort it out Doc. Pretty sure there has been a new pickguard put on with what looks pretty heavily modified from how it came out from the factory. Strange why the middle pickup is so close to the bridge pup and that switch orientation.
Have you had a chance to look at the wiring yet ?
So is the jack side mounted ? what I can gather on that photo of the series the jack was pickguard mounted but there is now a 3 way switch there
