Larry,

I like the psychotic look on the pilot's face.    n~

One of my 40VFs has TG stamped on the bottom of the lug, the other doesn't have anything. The 46VF has JD.   Hmmmm......

Randy, Et Al:  That's the Manufacturing  Lot or Batch number, and tells approximately when the engine was produced..  IF O.S. would only publish what letters correspond to what Month...?   Cheers, Glen
