Eric, I think what Rich is saying is that you have the answer right in front of you. You have shown that you possess an extensive library on Lugers. Researching on your own should be easy for a former attorney. There are plenty of videos on the net which will teach you how to disassemble a Luger without losing any parts so you even have a "hands on" answer. Won't it be gratifying to do it yourself.
