I'm afraid I have onl the auction house picture for this, which doesn't show the whole sword, but at least the most interesting bits are visible.

Of course more detailed photos when I have it in hand, however I thought it's interesting enough to throw out for comments now.
It's a 19th century piece with a southern style hilt, looks to be a blade of good quality with well struck half moons. However what interests me is the base of the blade and the odd way it's mounted. I've never seen this type of a flange on a takouba before. It reminds me of Indian weapons such as the khanda.
Anyone seen this style of mount before in takouba or kaskara? I have no idea if it's an established variation, something borrowed from the sub-continent or just a random one time innovation by a local smith.
I've attached the forum sized picture and here's a link to the
much bigger original.
