On you second question - the pana butta dimensions; one thing that to me makes a lot of the kukri mystery and magic
is: there are never clear answers. Most likely there are as many different pana butta handles as kukris with
that construction. So the only thing I can serve you with is a range of these handles as the shape would largely
depend on the time that it was made - and the hands of the owner, if custom made. But also in pattern made kukris from
the same period (e.g. MkIIs from 1917-1918) there are lots of variations. So please find attached two pictures of full tang
kukri grips in my collection that show some of the different shapes and the pommel constructions.
