FC3S Murray's never ending build.

That is hard to tell..... are the etchings the same "font" for the C and the D - almost looks like they are which would make me think its a D rotor on the rear? Not to mention, it appears the "D" and the "C" from each rotor are facing the same direction where the "E" seems backwards. If not, I would assume your rear is an E rotor, but that E looks like it has a little overlap on the middle line which would not happen in general machining stamping...

Since the motor has been apart before, its hard to really know - but generally the motors I've seen are C/D combos. From what I understand, you can use C with anything but you can't jump a letter such as a B with a D, etc.

Not sure if that helps, but food for thought...
