Nice looking kukri, it looks like the style Atlanta bracket as "Bhojpure" thats counts as a "perfect" scabbard as well, still with its original buttons & loops.
Intresting if that is the tang , its a very poor shape, i would hope its a bit of old shrapnel or some other damage though. If it is the tang it would explain the crack though.
Of all the Atlanta kukris these are the ones I am least sure about. If Nepali army, They could be c.1870 they could be WW1.
I have a suspician they may have been for Brit. Gurkhas rather than the Nepali army though, if that turned out to be correct I would say they are more likley c.1870- c.1900. {Victorian}Thats my personal opinion , but theres not much evidence about these ones.
What did you do bring the rosewood up like that? I assume it turned up black with dirt,cosmoline ,blood,sweat & tears?
The crack it its handle would make me say I wouldnt rely on it for chopping trees,{particularily if that is the tang.} I am sure it would still manage a few more humans though or spliiting thin pine board kindling or other light duties..
I wouldnt do any heavy chores with it unless your happy to re handle it if & when neccasary?
It probably has a longer temper zone compared to modern kukris but will be tempered just shy of file hardness, to enable the soldiers of yesteryear to sharpen it in the Field.
