This is not my area of interest, but finally I want to find out what I have… I suppose this is a WW2 K98 bayonet marked Berg& Co. Also I found a numbers/digits. Please find attached photos.
I couldn`t find any dates, I found before on this forum great information that it should be 2 digit date at the back of the blade, near the crossguard (Berg& Co) Unfortunately no visible date on my bayonet.
Is there any chance to find out if this is a early, mid, or late war, and if this is a common example? I will greatly appreciate any information. Thank you

Kind Regards
Alex
