I did not at any moment consider you being disrespectful, Jeff, in fact I was feeling a bit frustrated myself at first thinking I did not have a clue what you guys were talking about. However, as the topic developed I began to understand more about what was being discussed. But it still hasn't absorbed in yet that there is in fact different types of cases for different serial nos, albeit, the cases with the open back that can show the pushers, etc...
