Joe, to answer your question about the AH,BH,CH grades, the "H" stands for hammerless. If a gun was an AHE, the "E" would stand for ejectors. Your gun was a "T" grade hammer gun. It was the lowest grade Parker made in hammer guns in 12 gauge. Parker used many different letter grades in hammer guns such as T,R,S,U.L, etc. All were lower grades until you get to P,G,D,C, etc..
