Forgive me, wasn’t sure which section this one belonged in!

Picked this one up from a show last year, a last minute purchase on the way out that cost me £30. The seller informed me it was of World War 1 vintage, although from the research I’ve been able to do it is in fact much older. I’m almost certain it’s a traditional Nepalese one, clearly made by hand. It was in a box with several others, all in fairly bad shape.
I scrubbed off the surface rust that was on the blade, for fear of it spreading. Apart from that the tarnishing is minimal.
There also appears to be some sort of marking on the base of the handle, although I have absolutely no idea what it is or what it means.

Would be very interested to know more about this one, as it’s very much outside my area of interest and was bought more as a curio than an item of militaria.

Many thanks.
