Mike, I do not see a nut behind the hands attaching it to the face.  I'm pretty sure it is an original clock.  I think the clock is attached to a piece of wood and that is bolted up behind the face as shown (but I've never removed it):

   

I think your idea of having yours repaired is a good one.  Even if it isn't original it is still an older electric movement and you know it will fit.
