nice old one, the braised tang repair if done correctly should hold it together reasonably well, but it's probably not up to full combat efficiency. should clean up well for display tho. the scabbard bands appear to be braided 3 strand turks head style, not twisted, which you could replicate for the one that appears to be missing. here's a link to an excellent thread here on how to make them in rattan, which if you are careful and practice for a year or two would work for wire.
