What @Bassassin said.
My first thought was an Ibby with the mudbucker neck pickup, but on closer inspection that wouldn't have had the bodged cutout in the pickguard.
As to why someone did that to the pickups, I don't know; it looks barmy to me!
The neck joint must be weak there, so it might need filling and re-cutting.
The changes are reversible and stock Ric parts will fit, in addition to vintage Japanese and current Retrovibe replacements.
This is my (Japanese) CMI, which I would say likely came off the same production line.
The slightly translucent pickguard shows more on mine, against the jetglo body.
