The P4 module has a PCB with display, light sensor, IC and trimmer(I think), all in one. He has used the P3 plastic carrier(which holds the P3 reeds in the correct place), so that you can't tell when looking at it from the batteries side. All that he has to do then is remove the old innards from the P3 carrier, and then attach the P4 unit, attaching the old reed switches, battery terminals and QC.
Better than a dead watch. Unless you can tell by the display style, it's hard to tell such a modification on Ebay, without pictures of the module. Unfair really, since the real value of the old Pulsars is in the original working module.......with some exceptions of course !
