So how did I help you come into this piece other than not bidding high enough on it?

In my opinion, a nice old example of this type of sword. They are not terribly common and I think the blade is an older blade. Whether or not the marking is original or not is hard to know. The mark was copied everywhere so the blade really could be from anywhere. I think there was a preference for thin blades in this region. I once had a Omani Saif that had an almost paper thin straight blade but it was as sharp as the dickens. Usually when these things turn up, the blades show signs of much use so the thinness may also be attributed to a long service life. In my humble opinion, this one has a 17th-18th century blade in 19th century mounts. Add some sharkskin or leather to the handle and I think you have a good honest example. Congratulations!
