WELCOME TO THE FORUM
A VERY INTERESTING ITEM YOU HAVE IT APPEARS TO HAVE A GOOD OLD PATINA AND SHOWS GOOD WORKMANSHIP. IT IS A BIT OF A PUZZLE AS IT LOOKS TO BE TOO LONG FOR A SPEAR OR LANCE HEAD AND IS LONGER THAN THE BUTT SPIKES I HAVE SEEN ON SPEARS AND LANCE. YOU MIGHT WANT TO ADD THE DIMENSIONS ON IT.
PERHAPS IT IS THE TIP OR BUTT SPIKE FOR A STANDARD OR REGIMENTAL FLAG. I ASSUME THEY WERE USED BY THE ISLAMIC ARMYS AS WELL AS BRITISH, ECT. JUST MY BEST GUESS
PERHAPS A MEMBER WITH MORE KNOWLEGE IN THE FIELD CAN GIVE YOU SOME GOOD INFORMATION AND INTERPRET THE INFORMATION. GOOD LUCK
