Thats is a very lovely & to some collectors a valuable kukri Tim. Its a good one.
The weight helps see whether they are fighter or utility piece or indeed both in design. Just a glance says yours is a fighter though.
Thats defintly 19th century,
Well made , high quality piece, The scabbard shows Indian origin.
That was a good box of junk in my boo!
I doubt if I have much in my collection that you would be after, but its possible.But cash is no problem if you decide its not the piece for you. To me I would say it looks like a keeper though.
