I agree that the OP's FRG01B is legit, it does follow the same format and size, and in file and bitwise compares it contains most of the same files as the odexed rooted and unrooted FRG01B and FRG22 that have come out recently. There is little doubt about it actually coming from Moto or Verizon or Google...
However, for whatever reason, the OP's FRG01B is *not* the FRG01B that has been coming out in the "official" live OTA from Verizon's servers (and is also available from Google's website) for the last 24 hours. That one is much smaller and contains significantly less files.
I've gone through and compared a number of files in common between the FRG01B here in this OP and the one coming from Verizon/Google, and in bitwise compares they are the same. I have not compared everything though, perhaps someone else has completely done that footwork. But I have to wonder what functionalities have been left out of the actual official live OTA FRG01B that were in the OP's FRG01B, and what the rationale was for those differences.
Ultimately, the official live Verizon/Google OTA update's FRG01B is going to set the standard for "stock". If there are any important service related problems, this official live OTA version, with it's smaller set of files and everything, will be the ultimate judge of "stock" Droids.
