It seem as if the discussion has chosen a track of its own, and I think we should try to get it back, to discuss your latest sword (see how easy it is not to mention tulwar/tegha)
The blades I have seen of this kind have been curved a bit more or less, but never to an extreme. The yelman can be more or less pronounced. They have no fuller or only a broad single one. They are all broad and heavy blades, and they are 17th or early 18th century blades.
