Would not be surprised to see wootz blade.  Pattern-welded at the very least. Etching a small window will give an answer, but it would be an easy task: no rusting, no pitting. Not sure about the fittings: on the photograph they look copper alloy to me. Again, a small area  rubbed with silver-cleaning paste would direct you to their full cleaning or leaving them as is. 
Outstanding example of a true museum quality! Congratulations!
