CanadianAR meant the number on the bayonet blade should match the number on the bayonet scabbard. The Mauser bayonets with serial numbers that matched those of the rifles were typically found on Mauser rifles that were contract-made in Germany for foreign countries. Yours is a German S1884/98 III Model made for the K98 Mauser rifle, but also used with your G24(t) rifle. Unfortunately, the blade looks like it may have been sharpened post-war.
