Ok, I apologize for leading anyone astray. The only reason I had the sim out was to put in a back up phone while my nexus 6 was updating.
So indeed it was MRA58N.
I reflashed LMY47E with the SIM IN and went through all the updates and such and now I'm back on the Verizon Tracks - Version is now MRA58R, November 1, 2015 security path, Android 6.0.
Again my apologies - now I'll just leave this alone and let the updates come over the air!
