Early Islamic(?) Battle Axe

[RSWORD]

Would love to get some feedback about this item as it is a bit outside my area of knowledge but I probably know enough to either get me in trouble or make a good find. This axe has some characteristics that seem early to me. I lean towards an Islamic origin of this piece based on the shape of the head. I am not familiar with any European battle axe with this shape head. Please correct me if I am wrong. I find it interesting how the blade goes all the way down to the wooden haft, not unlike some Mamluk examples. The most exciting part of this example is the deep makers stamp. Does anyone recognize the marking? It looks like a fish to me and I do know many early Islamic swords in the topkopi are marked with a fish, granted a longer, skinnier fish, but a fish nonetheless. It is put together in an interesting fashion. You can see an obvious join on one side but on the opposite side of that the join is in the middle of the area between the crescent head and the "socket". The socket is forged in one piece. The handle was inserted into the socket and it appears a metal cap was welded on top to hold it in place. It really seems to have a lot of age to it and I look forward to opinions on this item.
