Two more that I do not know, so any help appreciated.
And thanks to those who have given me answers so far on the others.
I understand the code number etc. on this head stamp but am I correct in the K - K at 3 and 9 o’clock stand for Karlsruhe?
Drill round as it has a wooden bullet and I am assuming F.A = Frankford Arsenal? (OK, so I got that bit wrong…)
3 & 4 have me totally lost.
