Yes its a nice ASG88/98 bayonet from WW1,plus is the unit on untypical place stamped of spine of handle, i believe the frog is WW2 as secure strap was not used prior 1936, so the steel rivets speaks for timeframe 1941-45. I believe there is B.M.K.140 and some unknown stamp behind. Its a war time unit so its harder to deciphere as by prewar exact unit manuals. K could be Kompanie or Kolonne.
