George, the only thing I can tell you now is that it is a Field Grade and someone either sent it back to the factory for the engraving or had it done by someone who copied the Specialty pattern.
One last thing, look at the checkering, on a Field Grade it was 18 lpi, on a Specialty grade it should be 22 lpi. Plus what is stamped on the receivers water table, should be R E19285 and near it an S for Specialty. Loosen the trigger guard and look for the serial number there too. Inside where the sideplaates come off, there should be an "S" stamped there. Lastly like Revdocdrew stated get a letter from Cody, put down everything that you posted, serial numbers, barrel length, etc.
