Where did you get the alligator's head? Was it some sort of place that sells them? The code might mean something about the number of the head as was prepared by a taxidermist and also the initials might mean who prepared it.

The head was given to me. I still ahven't been able to track down what the code means

If you make your inquire of a taxidermist, then they might be able to tell you what the numbers and letters mean.
