help to identify newly aquired old yataghan

[mavi1970]

the wood inside the scabbard looks old and not a new peice or new peice distrissed to look old, its really worn down. also the leather is stitched together with a steel wire if sorts, which has actually held it together if it is as you say 100%old and original, the brass end peice also has little indentations around the area that covers the stitched leather center, as to almost be like little nails to hold it in place. the top end of it has a leather peice which has tiny sew marks along the bottom and top and along the seam. the design is one that interests me because it almost matches the design on the blade of a circle with a davids star of sorts.
