I looked at some other photos of T40 bridges and it looked like there was a U-shaped saddle held in place with a screw.
But Dave, you're right! Nothing is missing - just the pipe added.
This photo (found on the web) helped me see my error. The screw I saw is just part of the bridge mounting, and the forward part of the bridge has no role in intonation. The saddles are built into each unit which contains the individual string anchor.
That means something really major is going on with that bass, with the additional lift the pipe provides.
