Hi Stu,
I'm sure we've all seen a lot of modern Indian daggers with these Parrot head hilts.
But as has been pointed out, there is a tradition of using them.
I'd say from looking at yours, that the 'beak' although on the face of it seeming like a bad idea, would possibly not interfere with a grip as there seems to be enough room for a little finger under it. The gap seems sufficient.
Without the parrot head, this would be a big koummya/Shula. For me the blade and scabbard are not different enough from examples I've seen to raise any eyebrows (apart maybe from the size!).
As for if it was made by a Moroccan who'd seen an Indian dagger or an Indian copying a Moroccan form or even making it for a Moroccan customer......
Could be any.
My first thought was Indian in the Moroccan style, but the decoration and construction remind me of native koummya.
Koummya even turn up with imported european blades made in the traditional form.
So, no conclusive answer, but I'd spend some time comparing construction and decoration once you have it in hand. That should complete the puzzle.
A nice thing actually.
some good old threads on Koummya:
