that bayonet i showed you is for a Turkish variant of the K98. often times when other countries contract a design, they make modifications to suit thier individual needs... examples are the Czech SA Vz.58 (Kalashnikov AK-47) the Swedish Bofors AK5 (Belgian FN FNC) and the Chilean FAMAE S.A.F. (9mm Swiss Sig 550). That bayonet may only work for that turkish rifle. I'd contact the webmaster of that website and ask him, or someone else. usually you would go by markings for ID... that is why they are put there.
