Hello !
In fact the CPE2 motor was an SWF made. It was made for a very long period of time (the wiper motors are somewhat generic, so using and re-using the same assembly makes for a lower price). It disappeared when SWF was bought by a bigger company then again bought by a bigger one which rationalized production (every company has such generic equipment parts, so as SWF was the smallest with the smallest share it had to go).
If you can devise another way of fixing a wiper motor into your Jobo, you'll be safe because there are a lot of equipment out there with very similar capabilities (how many cars have wipers ? ;-) )
As per re-winding a worn out motor, I bet it is not the bigger problem you'll face. IMHO the gearbox will die before the inductors or rotor...
