Let me just add my emphasis to Kai's. Looks like a seperate gangya which would put it pre 1920, the tongue of the beak is horizontal to the gangya and there is no shoulder under it (traits of a Magindanao blade) and the curves are definately not uniform another plus. I think you have a very nice old blade, curious to see what the vinegar bath reveals.
As for repairs, well I personally - having been broken and fixed many times, am all for quality repairs, I like to think they add to the character of a piece
