I was reading the Herters headstamp topic and looked through the few 9mm that i have. I don’t have the Herter’s ones but I do have two with the following headstamps
H^N 44 9M/M II Z
H^N 44 9M.M.
the “^” is supposed to be a British Broad arrow but my keyboard doesn’t have one lol
I looked through the headstamp code section on the home page. Am I correct that these two rounds were manufactured in the Royal Ordnance Factory, Hirwaun, UK ?
