Did you lose it or break it? If it's just broken, let me tell you, It's SIMPLE to fix if you can weld! I just repro'd a complete hammer spur to my liking in about an hour and a half including grinding, polishing and oil blackening. Put the broken bit on a piece of brass and start building up the weld. When you have a good solid 'blob' of steel, start shaping with a grinder or dremel. polish, then heat the whole thing to cherry red and quench in a jar of oil. (smokey so be careful). Any flaws, just tack-weld the spot. Good luck.
