So even if I did open the 50g, I wouldn't be able to say more than that.

If you look in the picture, there's an actuator piece that pushes onto that contact or not depending on the switch position. At least you'd be able to tell if that actuator is broken, bent or stuck.
But if newRPL works, that proves that actuator is broken without opening the 50g. The stock firmware added support for that write protect pin later on, it wasn't supported at first, so you could also use an older stock firmware to test. I can't find any reference to which GPIO pin that is, otherwise I could perhaps give you a a couple of POKE's to try to force the firmware to bypass it.
