Meh?
Looks to me like they replaced the bridge with something smaller. Or are those screwholes from a bridge cover? I'm not very knowledgeable on Fenders, but something was there at one point that is now gone.
Well, I hate to say it, but you're wrong on this one.
The long G intonation screw is correct for Fenders up until late 72/early 73. They started using it along with the non-threaded saddles in late 69. In 73 they changed over to a G string intonation screw that matched the length of the others. The saddles are the correct diameter smooth single groove style with slotted height screws. Plate looks correct too, note the radius of the curves.
The screw holes you see are for a bridge cover. The two "lowest" ones in the pic that are about at the halfway point on the bridge plate are, more precisely, for the Precision style bridge cover. The other two that are further up on the body are for a Jazz Bass cover, which was obviously on this bass at some time..
