How did I miss this one? It is very nice, from what I can see.
I am going to go against the tide of opinion and say that it is Burman (as in the tribe after which Burma is named). The wide fuller and floral lotus pommel say Burma to me. Compare it to this one, which I am certain is Burman based on the presence of koftgari (plus the Burmese script is a dead give-away
).
I have seen the peg in a number of scabbards, so I think that it is a normal feature, but I don't think that I have seen it together with a chape. I think Andrew is right about age. Never seen the mark, either. It looks sort of like a flower with a stem ... or maybe a latanka? Are there two marks or one?
