This is a hammer advertised as 16th c. Polish... only the head appears to be original. I have no idea how you could get a replacement cap, but this is what mine looks like.
I think yours is a version with an axe blade at one side and the hammer on the other? I think the Poles call them czekan and the Hungarians fokos. There are so many different versions. Generally it seems the names suggest Turkish origins (via Hungary) for these weapons. You can read more about them here: https://polisharms.com/warhammers/
Iím quite happy with my Horsemanís hammer as it is without the top cap. Itís exactly what I wanted for my display.
