Answer I may have a partial answer. The capital letter in a circle stamped on your gun sounds like a proof mark. To proof a gun, it was fired with ammunition loaded to several times the power of a normal load.
This was done to ensure the safety of the shooter. If the gun survived the test successfully, a proof mark was stamped on it to show that it was a safe, tested gun. I don't know about the rest of your question, sorry.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
