Polish Hussar Lance/Spear examples?

So true. A thought just came to me: if we are to assume that this weapon is indeed of Polish origin, and since from our discussion so far it doesn't seem to fit the description of the kopia associated with the hussars, could it possibly be a regulation pattern used by some other type of Polish military unit? If we had an idea, it could guide us to search in other areas.

The vexing thing is that there seems to be no other comparable examples in existence. At least to our present knowledge. Hopefully the historical military literature might provide an answer, or at least a clue.
