could the 'double duck' mark be a letter Z in cursive?
(perhaps intertwined with another letter)
the other mark after the Krupp Laufstahl bullet, which also appears on my gun but only as a fragment I can't make out - perhaps something to do with Krupp Laufstahl?
Looks to me like a walking man in your photo

Best regards
Günter
