Typically for "Yugo-reworks" is the number upon the crossguard and frog-stud.

Normally "Yugo-reworked" bayonets are showing there flashguard but, sometimes, it was removed and the bakelite grip-plates were replaced by "Yugo"-made wooden oneīs ...
I agree, almost definitely a Czech bayonet, post-war. It will fit on a
K98 but is not German and was not made before 1945.
My reference point for my comment is based on the K98 bayonet which I have and also the Czech bayonet which I did have but sold. The K98's were of much better quality and were generally longer. Also, the hand-guard on yours looks almost new.

Its typical yugo rework, i dont know from what sources they came the "czechoslovak" roots, as czech didnt exist separately postwar. In all pictured bayonets are yugoslavian M24/48 frogs, so is no doubt about the origin of the rework. Czechoslovaks didnt rework SG84/98 bayonets in large quantities and the rework is so done that is hardly determine from german production, not so crude as here.
