In the photos that Jon has just posted all the radio gear looks like 19 set generation, remember that the 19 set generation of radio gear was replaced by the Larkspur system which was in turn replaced by Clansman which was replaced from about 2000 by Bowman. The best resource on Larkspur that I use is:

In the photos of JXW32you can see the FVPE 'wing' (individual vehicle identification number): 3816, and 'P1' telling us that this is prototype number 1. All the other prototypes will be significantly different in detail and often in major ways like hatch arrangements, power train, etc.
Note that P1 has no provision for the wading screen which I believe was bolted to the top of the track guards and into the notch in the top of the rear stowage boxes, against the rear of the hull armour.
