Help with W.W.1 British? cavalry lance

[spiral]

Nice, not certan the stick is original though....

The hand cut stamps used to make the markings are not as precise as the British ones. There look typical early ww1 era Indian made stamps.

obviously 1915 is the date.

Co. Could be the maker or inspection base mark, Co usualy stands for Cossipore a well known British Indian arsenal.

Is there an I under the broad arrow above the 5 ? Looks like there is? Thats the Indian goverment mark.

can you take clearer photos of markings. The 5 is the inspectors number

N2.1.1.P will be a unit marking, the ones might stand for I as well.

A unit marking ending with a P word could be a police unit perhaps? {just surmising, that one.}
