During this search i have gained a lot of information, specially that i am these days reading The Dan Brown book "The Symbol"

But i am still confused of the name, year of this bayonet?
Why there is no any serial number on any part of it as there should be?
Why the letter "Z in a circle" is engraved on it?
There is no other sword or bayonet made by Alex Coppel that has this mark besides the AC scales?
I know that these are a lot of questions, and that the KOTCT is about coin collecting but i just need help, so i appreciate if anybody can answer these questions or reffer me to who can.
Regards
