Vintage No-Rad FF- Real or Fake??

I have the chance to buy the vintage FF. I saw if today and took these pics, which didn't come out well at all on my phone. I know you're very knowledgable about these, could you give me an opinion on originality? From what I've seen, I have some doubts about it, but I'm no expert. The seconds hand looks wrong, the hash mark at 6 o'clock looks too long, and the no-rad symbol had a hint of a green color cast that doesn't show up in the pics. What do you guys think, good or no good?
