Are you sure about this? Side by side to my Freeman, '70s, '50s and American standard the new '60s looks like normal plastic whereas the others are almost the same, especially the Freeman and the American p. Here's some pics to give an idea. 70s, 50s, Fremann, the Fender and last the 60s.

The bone nut use on Pre CIC CV bass is synthetic bone, kind of hybrid plastic bone, milky colour when new then turn to light brown after couple years usage.
The nut on New Indo CV has same kind of material use on VM bass, appear whitish in colour.
Since FMIC move all the CV line to Indonesia, sure they will continue use those same part which use on VM and Affinity bass.
On my previous Indo CV50P, the bridge is aftermarket kind of Fender vintage bridge. Actually it is fine. Just the tuner are not tuen as smooth as my CIC 60P, 50P and 60J.
