This one was odd enough to tempt me but, in the end, too odd to bid on.
The missing chape is unfortunate, and the silver sheathing looks loose and the wood beneath newer.
I think we're looking at a recent (i.e. mid-late 20th c.) ceremonial/presentation sword. However, the blade looks promising as I think I can seel a "hamon" along the edge, even wrapping around the tip which could indicate differential hardening or an inserted edge. My eyes could be deceiving me because of the poor pictures.
